people forget that tcu is not a powerhouse historically -- gary has the best winning percentage since francis schmidt (1929 - 1933)
most the records in between when gary started and 1933 are .500 and below
if their big cigars have someone lined up who is young and they're confident in (like a stoops -> lincoln riley deal), I don't think it would be a horrible idea to make a move, but historically speaking there's a bigger chance of potential downside than upside -- unless they luck out with the right guy
