Reggie Bush said Wednesday that the Detroit Lions' lack of discipline has hurt the team during a span in which it has lost four of five games and ceded control of its playoff destiny.

"It could be from penalties or it could be from turnovers or it could be from how we finished the games in fourth quarters," the running back said. "It's not one specific play or moment in a game. It's the total game. It's how we play."

Bush, however, pinned the team's discipline problems on the players and not coach Jim Schwartz, whom he called a "disciplinarian."

"It's not a coaches' thing. It's a players' thing. We can do a better job all across the board," Bush said. "As far as an offense standpoint, turn the ball over and that's the discipline issue, and that's something we have to correct, because obviously, as you see, it'll lose you games."

Schwartz said Wednesday that he wasn't aware of Bush's comments but that he doesn't believe the Lions have a discipline problem.

Receiver Nate Burleson agreed that the onus falls on the players to fix their issues.
