If Urban meets Saban again as the head coach of our Buckeyes I truly hope that he grinds him into dust.
However, I must disagree with your statement that Saban is not a great coach.
You state that he is doing nothing innovative, ground breaking, or creative. It may appear this way on the surface but Saban's real genius lies in the way he teaches his schemes. He definitely teaches ground breaking techniques to his defensive backs (they are not coached to back-pedal, 90% of other teams are) and he is widely considered to be one of the most innovative defensive backs coaches in the country at any level. He teaches the most sophisticated defensive scheme in college football in such a way that his players know their jobs so well that there is no hesitation.
The reason what he is doing defensively doesn't look that innovative is because many teams from around the country run variations on his defensive scheme. Even today Ohio State's defense (originally brought by Mark Dantonio) uses the EXACT same terminology as Saban's for many calls. The defense we used to win the national championship is the exact same defense, word for word that Saban used to win at LSU. Now, each scheme has evolved over the past decade to adjust to their available personnel, but the base remains the same.
Saban is not super involved with the offense (kind of how Urban is with our defense) but he makes sure that the offensive game plan is set up to control the tempo for his defense and score enough to win. Does it always work out perfectly for him? No, but his teams are tough, disciplined, and flexible enough to make adjustments.
I'm not arguing that Saban is the best coach in the country or that he is better than Urban. However, the man is a great coach, not based on WHAT he does but based on HOW he does it. Great coach or not, I still hope the Buckeyes take him out behind the woodshed in the title game.
