Only in Detroit can we go from a secondary signing to high profile CBs, a very high profile Safety, have a rookie showing up like he's headed for the pro-bowl... and now the unit has turned into a liability.
I am firmly of the opinion that some people who are excellent coordinators are just not cut out to be HCs. That's not a knock on them... there's only 64 NFL coordinator positions in the world (not counting ST coordinators I guess) so that's a very, very high achievement to reach.
Being a HC requires different skills than being a coordinator so we shouldn't just assume great coordinator = good (or great) HC.
I don't know if I agree with that. Now obviously this is a simplistic stat line, but the Falcons have a LOT more yards than the Packers did in that game.
