Hall of Fame
OB is exactly that: mediocre as a HC. His record of 52-48 proves that. That's the best he could pull off with the rest of the ACFS being a dumpster fire for the vast majority of his tenure. If .500 ball is what you're looking for, OB is your man.By virtue of his record of winning 4 AFC South division titles in 6 years I think O'Brien deserves to be labeled at least a mediocre NFL HC.
I dunno but I think it's 4 out of 6, maybe I'm mistaken about that ?
