Green Bay Packers linebacker Clay Matthews does not understand why he was flagged — yet again — for roughing the passer Brett Favre Jersey , this time while sacking Washington's Alex Smith on Sunday. Matthews think it's an indication that the NFL is "getting soft."Even Smith wasn't quite sure about the call that came late in the third quarter of Washington's 31-17 victory. Neither were other players — or the coaches — from both teams. Matthews broke free into the backfield, grabbed Smith with both arms and took down the QB in a seemingly straightforward manner."When you're tackling a guy from the front, you're going to land on him. I understand the spirit of the rule. When you have a hit like that, that's a football play. I even went up to Alex Smith after the game and asked him: What do you think? What can I do differently?" Matthews said."That's a football play. I hit him from the front, got my head across, wrapped up. I've never heard of anybody tackling somebody without any hands. When he gives himself up as soon as you hit him, your body weight is going to go on him."There are sure to be more questions and more debate around the NFL about what constitutes a penalty on such plays."I had judged that the defender landed on the quarterback, when he was tackling him, with most or all of his body weight, and that's not allowed," referee Craig Wrolstad said, according to a pool report. "That was basically my key — that he landed on him with most or all of his body weight."Matthews immediately put his arms up and slapped himself in the helmet as the flag was thrown. Packers coach Mike McCarthy threw down a play-calling sheet and argued with two officials about the call, yelling while chasing one along the sideline."I think Clay did exactly what he's supposed to do there," McCarthy said. "He hit him with his shoulder. He was coming full speed off of a block. He braced himself. So I was fine with what Clay did."In Green Bay's 29-29 tie against the Minnesota Vikings last week, a potentially win-sealing interception for the Packers was wiped out by a roughing call on Matthews when he hit Kirk Cousins."Unfortunately, this league is going in a direction that a lot of people don't like. I think they're getting soft. The only thing hard about this league is the fines they levy down on guys like me that play the game hard," said Matthews, who actually was not docked pay for that hit on Cousins. "Maybe now pass rushers, guys getting after the quarterback, you'll just have to attack the ball."Smith's take on the hit he took from Matthews?"I'm glad I don't play defense. ... They can't hit us in the head and can't hit us in the knees when we're in the pocket. It's tough. I felt like he was playing football. He's played a long time. Hit me right in the strike zone," Smith said. "That's the new rule they put in, though, with these guys finishing quarterbacks to the ground."The rule preventing defenders from landing on the QB has been around since 1995 Adam Thielen Jersey , but the league's competition committee made it a point of emphasis this year. More than 30 roughing-the-passer penalties were called in this season's first two weeks."Every week," Redskins coach Jay Gruden said, "there seems to be another one that's a little bit questionable."With a heavy sigh, Matthews said: "Nine years, I've been doing it one way in the NFL, successfully, and now it just seems as if that way doesn't work anymore. And that's frustrating."Not surprisingly, Packers teammates agreed with Matthews. Perhaps more surprisingly, so did several members of the Redskins."Oh, my gosh. Look, I'm glad it was for us, but then when I looked at it, I was like: What else do you want the man to do? Seriously, what else do you want the man to do?" Redskins cornerback Josh Norman said. "When I saw it, it was not malicious, ill intent. It was just a nice form tackle. ... I'm lost by it. I'm pretty sure (Matthews) is frustrated and he has a point." The Vikings got running back Dalvin Cook back on the practice field Friday, but it’s unclear whether he’ll be on the field against the Eagles on Sunday.Cook is dealing with a hamstring injury and he has been listed as questionable for the trip to Philly. Cook did not play the last time the Vikings visited the Eagles as the torn ACL he suffered early in his rookie season kept him from taking part in the NFC Championship Game.Latavius Murray, Mike Boone and Roc Thomas would be the Minnesota backs if Cook can’t play.Cook is the only Viking listed as questionable, but they did rule out four players. Cornerback Trae Waynes remains in the concussion protocol, which will leave cornerback duties to Xavier Rhodes, Mike Hughes and Mackensie Alexander. Defensive back Marcus Sherels (ribs) will also miss the game.Defensive ends Everson Griffen (knee/not injury related) and Tashawn Bower (ankle) are also out, so the Vikings will be thin at that position.
