You can't really compare the situation at Akron to Ohio. While Knorr may not have improved the program, he wasn't a complete disaster, at least not on the scale of some coaches we've seen recently at schools like Akron or Miami. Using Sagarin numbers to compare (since they are readily available), the average for Ohio the prior three years under Grobe were 63.50. Under Knorr the average was 57.49, down, but not by a massive amount.
Let's compare that to iCoach. In the last three years under Brookhart, the average was 57.47. Under iCoach, the average was 41.58. No one else could do that, right? Well, the average under Molnar's predecessor was 57.45, and Molnar managed a 2 year average of 41.64. Thus, if you want to compare Bowden to someone, compare him to Whipple. Can Whipple pick up the pieces as well as Bowden did? Better? We'll have to wait and see.
Back to comparing Akron pre-Bowden to Ohio pre-Solich. Akron had gone downhill much faster, and was in worse shape, by far. On the other hand, Bowden got to start with a nice new stadium, and an indoor practice facility. I'd be remiss if I didn't point out that Akron also has malls, well known to be an important recruiting tool.

Thus, he started with a worse team, but far better facilities, and in an urban setting.
Bowden, in his first two years has raised the average from 41.58 to 53.05, a substantial improvement, but even now he doesn't have Akron playing as well as Ohio was playing under Knorr, or for that matter, as well as Akron was under Brookhart. If you want to compare him to Solich, let's see what he does from here.
