Retread Head Coaches

It also doesn't tip the scales in favor of a young first time head coach.

I agree.

It does not change the debate for either side. When the big debate seems to be McCarthy v Brady and it is brought up as a pro-McCarthy argument to say 1/2 the last 4 playoff teams have retread coaches, while not bringing up the fact that the other 1/2 of the last 4 had the same first shot story as Joe Brady - that is pretty misleading, isn’t it?
