marlon mccree is horrible, heck i'd take ferguson over him any day. the video below is from the vikings/chargers game last season. i took the liberty of pointing out a few of mccrees 'highlights'
1:24 - poor attempt at a tackle, leads to peterson touchdown
2:44 - completely whiffs
3:17 - missed tackle
3:32 - took bad angle and blown by, leads to peterson touchdown
4:11 - resorted to horse collaring peterson from behind
