The rules in the Canadian Football League are a little different than the NFL but football is football.

The Bears hired Marc Trestman after five years as coach of the CFL’s Montreal Alouettes and Chicago’s 3-0 start has proven he could handle the transition.

Trestman who won two Grey Cups has been called an offensive genius by some Bears players.

“He didn’t win (in Canada) just because it was 12 guys on the field and 55-yard midfield and everything else” Lions coach Jim Schwartz said. “He won because he’s a good coach. They’re 3-0 because he’s coached the team well.”

Trestman also has been an assistant with eight NFL teams including the Lions (quarterbacks) in 1997.

“I enjoyed the season there” Trestman said. “Barry Sanders was there in that year and I got to know him a little bit. I really enjoyed coaching Scott Mitchell. I thought he was tremendously professional.”

Lions players said they’ve noticed a few differences in the Bears offensive scheme under Trestman. The Bears put added emphasis on quick throws but once they reach midfield they will take deep shots to big wide receivers Brandon Marshall and Alshon Jeffery Lions cornerback Chris Houston said.
