I think Saban would've eventually been successful in the NFL. He went 9-7 in his first year and then was horrible in that second year (6-10). But, I think in time, he would've proven to have been a good NFL coach. I think if he ever decides to try the NFL again, he'll have suitors ready. Of course, he's worth about $6.9M and getting ready to make $65M, so why would he ever leave for the NFL?
