Israel Idonije says all the credit for the Detroit Lions' explosive offensive performance against the Chicago Bears belongs to the offensive players who executed their game plan.

But when pressed whether he had a role in that game plan which yielded a 40-32 win the former Bears defensive lineman didn't refute it.

"I mean I did anything anyone would do in a transition situation" he said. "Nothing out of the ordinary or unique to any situation.

"I'm a Detroit Lion period. My allegiance is to the Detroit Lions. I'm inside here. I have nothing to do with the other 31 teams. My focus is to help my team Sunday in Sunday out period."

Lions tailback Reggie Bush had a monster game against Chicago racking up 173 yards from scrimmage -- including 112 first-half rushing yards on just 11 carries.

But at least one unnamed Chicago player complained that Bush might have been operating with insider knowledge telling ESPN he believed Idonije tipped the Bears' defensive playcalls.

The unnamed player said he believed Detroit anticipated the Bears' power stunts.

Idonije didn't deny helping inform Detroit's game plan but laughed off the notion the Lions were reading playcalls in the game.

"At the end of the day no one goes in looking to read someone's calls" he said. "You're going in reading formations keys tendencies down and distance and then if you happen to hear a call or a color or something and it has some sort of repetition in the game you mark it down.

"But you don't live off that. That'd be foolish. At the end of the day it's about studying and execution and that's what those guys did."

Idonije tried to play down his first game against his old team leading up to the matchup but acknowledged Wednesday just how meaningful the victory was for him.

He spent nine seasons with the Bears but wasn't welcomed back this season and signed with Detroit.

"That was my family for (nine) years" he said. "Big picture it's just another opponent another game. But personally I definitely wanted to walk off that field with a W."
