Because Georgia was the only program running a shadow booster network that paid recruits or was the only state loaded with talent year in and year out? No in-state competition that no other program elsewhere tried to recruit? Everything you said sounds like the same tired, unoriginal, repeated talking points without a sense of thinking for yourself. Most coaches can't win the big game. Most coaches can't even get to the big games. Here's a fact. There were only 4 active head coaches this season who've won a title. 4.
Again, you can criticize Richt, there's fair criticism to be levied upon him for how he's had great talent and not been able to beat Saban and others, but let's not act like him not winning a title yet is exclusive to him. And yes, we have seen who he is. He took a team last year that had no business winning 10 games and got them to the ACC title game where they were without their 3 best offensive players against one of the premier teams in the country. They were a year early last year and weren't ready this year because they were hamstrung by a QB that didn't progress and actually got worse and his backup who didn't feel like midweek preparation was a big deal.
I choose to not bash the guy. If you want, you go ahead, but relying on his track record isn't "failing to realize" anything. I'm not going to declare next season a failure before a single down is played. All we have is his track record of being one of the game's better coaches and his track record says he's a 10+ win coach more often than he's a 7 win coach.
