Jimmy Andrews is what Alabama is promoting. While Iowa may have an excellent medical system, they do not have the notoriety in Sports Medicine. Unfortunately, notoriety sells. Take a look at the article, especially the list at the bottom.
While they may have equally good surgeons, and Andrews is 80 (does very little surgery now), this is what is sold to the players.
I can't get the link to work. But if you search Bleacher Report Dr. James Andrews: The Athlete's Surgeon you will find it.
