Saban IS a great coach. Before Meyer signed on at Utah, the Utes had a 71-45 record the prior 10 years before Urban came on board, and historically had over 500 wins and many bowl games before Urban showed up, so it's not like he stepped into a total loser program, far from it. Meyer certainly made the Utes better, no arguing that.
Meyer took over programs at Florida and Ohio State that had all kinds of talent, and didn't historically suck, so that narrative gets shot down.
Saban has had many assistants come and go at Alabama, but they still maintain greatness because Saban knows what he wants and his assistants coach the way he lays it out for them. To regard Saban as not being a great coach is laughable.
Check out the scores between Alabama and Florida in 2009, 2010, Meyer's last two seasons at Florida, total one sided routs handed to Meyer by Saban. Not great? I think not.
