Actually, I think these Packers-Bears games have become more of a fan-rivalry than a player rivalry. The players were damn near fornicating with each other there was so much love on the field after the plays and after the game. Seriously, I think Both the Pack and the Bears consider their respective Queens games as more of a rivalry, given how dirty the Queens have played in the last decade save for this year and maybe last year.
The one exception was when Favre took out that poor Bears corner, may have been Vasher, on that end around where Favre was the lead blocker. Favre went up to the guy after the play like "no hard feelings even though I just embarrassed you on national TV". Looks like he didn't even acknowledge Favre though. Why should he?
