Freeman's a good college coach with potential to be a great one. He needs more seasoning as a head coach.
One of the big reasons the pros are interested in interviewing Freeman is pretty simple: he fulfills the Rooney rule. Day at OSU and Smart at UGA have more clear experience and success than Freeman yet their names don't pop up. The other reason Freeman is farther away from a pro job is that he doesn't really have a rolodex of coaches he would need to hire a pro staff. His recent coaching searches for OC and DC are a pretty bad indicator that he needs to continue to build his network.
