I'll probably get flamed for saying this, but I am going to put this here and see how it ages over time.
I started going to games with my dad when Lewis Field was a street level (late 60's/early 70's). I saw us being a stepping stone for good coaches (Jimmy Johnson, Les Miles, and now Jim Knowles) which resulted in short term successes but no long term consistency. Gundy comes in and we finally have long term success and consistency (granted, the last 3.2 seasons were not consistent).
I think we will become a stepping stone again. If we do find a good coach, he will get hired away and we have to start all over again hiring staff and chasing recruits. Just my $0.02. Flame away.
