Saban vs. Spurrier is a tough call... very tough.
-Spurrier is an offensive genius, but relies heavily on others for a strong defense.
-Saban is a great defensive mind, maybe not on the genius level though, yet also knows a little about offense.
-In their prime, both are top notch recruiters, but Spurrier doesn't recruit with the same tenacity that he did at Florida. Saban is still a bloodhound. Both have a great eye for talent though, and both know how to develop it.
-As far as game day coaching and strategy, I'd say both are about even in that department, but it is hard to compare since both specialize on opposite sides of the ball.
Overall, it is pretty much a toss-up. If both were in the prime of their careers, it would be hard not to pick Spurrier... but if you are asking me to pick one today, I'd take Saban without much thought. There are some here that testify to the fact that Saban was my #1 choice when Shula got canned. Of course, I would have been plenty happy with the Old Ball Coach too.
