Last Thursday, a federal appellate court issued another decision in NFL commissioner Roger Goodells favor and against the NFL Players Association.This time it was in Adrian Petersons case. The 8th U.S. Circuit Court of Appeals held that Goodell was properly acting within his powers when he suspended the Minnesota Vikings running back, under the domestic violence policy set in August 2014, for conduct that occurred in May 2014.Heres a Q&A breaking down what it all means:What was the case about?It starts with Article 46 of the collective bargaining agreement, which allows the NFL to hold players accountable for conduct detrimental to the integrity of, or public confidence in, the game of professional football. This empowered Goodell to create the personal conduct policy.In August 2014, following the Ray Rice controversy, Goodell circulated a memorandum to teams, outlining enhanced penalties for personal conduct policy violations involving domestic violence. These penalties increased the two-week unpaid suspension to six weeks for a first domestic violence offense.This case was about whether Goodell could retroactively apply those enhanced penalties to Peterson for the domestic violence he committed four months prior to the rules inception.?How did the events play out?Two weeks after Goodell issued the memorandum, a Texas grand jury indicted Peterson on Sept. 11, 2014. The running back was charged with felony injury to a child, his then-4-year-old son, during a May incident.In November, Peterson pleaded no contest to the lesser charge of misdemeanor reckless assault. Goodell suspended Peterson indefinitely and fined him six games pay based on the protocol outlined in the August 2014 domestic violence memorandum.An arbitrator Goodell chose affirmed Petersons penalty, but a federal lower court reversed it. The NFL appealed that decision to a higher court.What did the appellate court decide?A three-judge panel on the 8th U.S. Circuit Court of Appeals agreed with the arbitrator, holding that Goodell could apply the enhanced domestic violence penalties to Peterson.?The appellate court did not think Goodells memorandum created a new penalty that could have been applied retroactively. Rather, the appellate court concluded that the August 2014 memorandum just further explained the then-existing personal conduct policy, effectively enhancing it.The court also said Goodell may issue whatever punishment he believes is necessary under Article 46 and the personal conduct policy because neither limit the commissioners authority. In other words, the League might change its discipline without changing its policy, the court said.What does the ruling mean for the NFL?The ruling means Goodell has the power to increase or decrease punishment as he sees fit. The commissioner isnt limited to prior discipline -- i.e., Goodell doesnt have to issue the same punishment to a player that he issued in the past. Goodell has the power under Article 46 and the personal conduct policy to punish players to whatever extent he believes is necessary to deter the bad behavior.?Following the Deflategate decision against Tom Brady, this ruling just reaffirms the expansive reach of Goodells powers when it comes to issuing punishments under the CBA.?What does the ruling mean for Adrian Peterson?The ruling doesnt impact Petersons ability to play. It requires only that he forfeit his game checks for the six games Goodell suspended him in November 2014. Thats approximately $4.1 million of Petersons $11.75 million salary. (After Week 2 of the 2014 season, Peterson was placed on the commissioners exempt list, so although he was barred from all team activities until his child-abuse case was resolved, he still received his salary. It was after he pleaded guilty to the lesser charge that he was suspended, without pay, for the final six games of 2014.)League sources told ESPNs Ed Werder that Peterson had already paid the NFL three game checks, leaving less than $2.1 million to be paid.What does the ruling mean for the NFLPA and NFL players?The ruling is another hit to the NFLPA. The back-to-back appellate court losses could deter the NFLPA from pursuing challenges to Goodells authority in the future.?With this 8th U.S. Circuit Court of Appeals decision, coupled with the 2nd U.S. Circuit Court of Appeals Deflategate decision, the precedent has been set that Goodell has broad authority under Article 46. The decisions give the NFLPA little room to raise a viable argument undermining that authority.That does not mean there wont be more discipline fights; in a different case, with different facts, the NFLPA might find it worthwhile to raise a challenge. Its the associations duty to defend the leagues players. ?How can the NFLPA change the breadth of Goodells authority??The NFLPA can limit Goodells powers in Article 46 only by negotiating new terms in the CBA.?The CBA can be renegotiated at the end of the 2020 NFL season. That is, unless the NFL and NFLPA collectively agree to change the CBA before that time. This is unlikely, largely because Article 46 isnt an issue that impacts a lot of NFL players. Said another way, relatively few NFL players commit personal conduct policy violations.And fewer are getting into trouble, period. As the Washington Post reported last week, there has been a 40 percent drop in the number of NFL player arrested in the first six months of this year as compared to the same period last year. That means the NFLPA might not make it a priority to negotiate a change in Goodells powers under Article 46 now and possibly in the future.?Adrienne Lawrence is a legal analyst who practiced law from 2008 to 2015 before joining ESPN in August 2015.?Follow her on Twitter @AdrienneESPN.

Lamar Jackson Jersey .J. -- Marty Brodeur beat the Pittsburgh Penguins yet again. HOUSTON -- James Harden blamed the added suspense on Rockets coach Mike DAntoni.Harden made a free throw with 0.1 seconds left, lifting the Rockets over the Dallas Mavericks 93-92 in their home opener Sunday night.Harden put extra pressure on himself by missing the first of two foul shots after being fouled by Wesley Matthews on a driving layup at the buzzer with the game tied.Coach messed me up, man -- he said, `Make the first one and miss the second one, and I did the opposite, Harden said with a smile. Im just happy I made it and we came away with the win.Harden led Houston with 28 points, seven rebounds and seven assists, edging Matthews in a gutsy back-and-forth.After trailing by 10 entering the fourth quarter, Dallas tied it at 92 on a 3-pointer by Matthews with 4.1 seconds remaining.DAntoni was pleased with the execution on the play that won the game. Nene received the inbound pass and found a cutting Harden with a crisp bounce pass before Matthews drew his sixth foul.Thats what he does, DAntoni said. Thats why hes one of the best, and hes just so good at drawing fouls and getting in the lane.Matthews led Dallas with 25 points and J.J. Barea scored 18 points off the bench. In falling to the Rockets for the second time in three days, the Mavericks fell to 0-3 for the first time since 2011-12, the lockout-shortened season following their title.We gave ourselves a chance, and it comes down to the one play and the whistle, Mavericks coach Rick Carlisle said. Were up against it right now in a lot of ways, but no ones backing down. Weve just got to find a way.Dallas was without Dirk Nowitzki (illness, sore Achilles tendon) for a second straight game. Nowitzki participated in pregame warmups but was a late scratch.Our margin for error is so slim, Matthews said. Were not the Golden State Warriors, were not the Cleveland Cavaaliers, were not the Spurs, but were a .dddddddddddd.. good team. So weve got to minimize the stuff that we can control.Houston got strong performances from offseason additions Eric Gordon, Ryan Anderson and Nene in their home debuts. Gordon had 14 points, Anderson had 14 points and 12 rebounds and Nene had 11 points.The Rockets capped the first and second quarters with points at the buzzer. To end the first, Corey Brewer hit a 3-pointer from 30 feet out. Harden ended the second quarter on a driving layup to put the Rockets up 63-53.Late in the third quarter, Houstons Trevor Ariza and Dallas Salah Mejri received double-technical fouls after both players fell to the floor and were tangled for a few seconds. Ariza clinched his fists before he was restrained by players.TIP-INSMavericks: Without Nowitzki, Dallas was frequently undersized but managed to hold their own in the rebounding category, with Houston edging the Mavericks 46-42. ...
