I'm sure the Bears coaches will pick this up, so I'm not worried about posting it. But last season Muhsin pwned McKenzie. MM has 2 pass int's called on him and Orton completed a 22 yard pass to him to setup the game winning FG when MM had man-to-man coverage.
That matchup worries me a lot. Muhsin (6' 2") is only 2" taller than McKenzie (6' 0") but he looked like he was 6' 6" in last season's matchup. I'm confident the Bears will test this matchup and I'm confident the Saints will be ready for it.
