Seth Joyner was a three-time Pro Bowl and All-Pro selection as a linebacker with the Philadelphia Eagles from 1986 to 1993. If he was ever tired, he never admitted it.

The same couldn't be said of current Eagles cornerback Byron Maxwell, who said he was fatigued after the team's humiliating 20-10 loss to Dallas on Sunday.

"This is the second week," Joyner told Comcast SportsNet's "Philly Sports Talk," via CSNPhilly.com. "Last week he was laughing. This week is, 'I didn't have anything left.' They're paying you $14 million. Are you kidding me?"

Joyner said he could grade the Eagles' defense as a 'B' product, if not for Maxwell. The corner's problem, Joyner thinks, could be the scheme he plays in.

"In a lot of instances, he is doing the best that he can," Joyner said. "He is a zone coverage cornerback. He is not a man-to-man cover guy. They put him in a technique that he's bound to fail at."

Maxwell has been less than physical in his first two appearances for Philadelphia (0-2), fooled and beaten by opposing team's No. 1 receiving options. Not that he's been too bothered by it.

Maxwell laughed off the 141 yards he surrendered to Falcons receiver Julio Jones in the Eagles' Week 1 loss and was seen smiling as he headed for the locker room after Sunday's game against Dallas. He permitted a 43 yard touchdown from backup quarterback Brandon Weeden to Terrance Williams.

"You're a human being," he said. "You get tired."

Joyner's too old school for that.

"I don't get today's NFL," he said. "These players play three or four downs, then their hand's in the air and they're running out of the game. I can't remember being out of a game. I never wanted to be out of a game."

That attitude, he said, might be attributed to the modern practice regime.

"I think that's why Mychal Kendricks pulled his hamstring, I think that's why Byron Maxwell is tired at the end of the game, I think that's why they don't block worth two cents, and I think that's why they don't tackle that well. Because you know what? They don't practice.

"You don't get paid the big money for being tired," he said. "You get paid the big money for playing and making plays and making it happen."

Maxwell finished Sunday's game playing on 96 percent of the snap counts.
