I was digging into that, and Eric B. seems to have all the pre reqs. He's even well loved by his peers.
But just because it seems like he deserves it, doesn't mean he should get it. Andy Reid is calling the plays, and Eric, for better or worse, has ridden behind that.
Eric B. needs to leave the chiefs so he can call plays and build the resume. Andy Reid is not giving up playcalling.
PS.. How many head coaches have you seen that are 5'7? Not that it matters in this, but I really can't recall many lol.
