LAKE FOREST, Ill. (AP) -- Bears running back Matt Forte isn't quite sure what to make of Green Bay's new 3-4 defense.
He says the Bears don't have much video of the Packers running it, so the rivals are a bit of an unknown heading into this weekend's season-opener in Green Bay.
Forte was a bit unknown himself this time last year.
He emerged as one of the NFL's top young running backs while setting several club records as a rookie.
He established Bears rookie records for with 1,238 yards rushing and 1,715 from scrimmage, and his 63 receptions set Bears marks for a running back and a rookie. He was also just the eighth rookie since the NFL merged with the AFL in 1970 to lead his team in yards rushing and receptions.
