This is a pretty cool run through with Bears wedge buster Israel Idonije.

Brendon Ayanbadejo, a two-time Pro Bowl pick for his special teams work (who was signed by Baltimore in March), is smaller and faster than Idonije and makes more tackles. That's because while Idonije typically tries to go through the wedge, Ayanbadejo runs around it and comes in from behind. This time, though, it is Ayanbadejo who makes first contact, knocking linebacker Stephen Cooper aside around midfield. Idonije's first line of defense is eliminated.

Thanks, Brendon.

OK, the wedge is forming to my left.

Once Idonije reads the play, it's all-out mayhem -- and he has a distinct advantage. He's a 6-6, 297-pound defensive lineman yet plenty fast for sprint work. As wedge busters go, he's a freak. For the fullbacks, linebackers and tight ends who typically form the wedge -- and, worse yet, for the returner -- the sight of a man that large moving that fast can be unsettling, if not frightening.
