Depends what you mean by excellent. Keatts has yet to win a single NCAA tournament game, whereas Groce took Ohio to 2 NCAA tournaments (Ohio gone to 1 NCAA tournament in the last 15 years), and actually won 3 NCAA games and got to S16, something that no coach at Ohio had done since 1964 - that is in the last 46 years before Groce.
There were positives and negatives in Groce's resume and Keatts' lack of NCAA success so far may be viewed as a potential negative as well.
Many posters try to make it sound that Groce was a terrible choice from the get go, guaranteed to fail, etc. etc. He was not. He was not on the A+ list (e.g., Shaka Smart) but neither is Keatts. Both with a reputation as recruiters. Some potential risks in both their resumes. The difference is that Groce has already failed, period. Keatts has not, so just the fact that he is also known as a recruiter, does not mean that Keatts = Groce or that Groce failed, so will Keatts.
Bottom line is that there will be risk no matter who we hire, but Keatts is one of my top 3 choices, meaning willing to take the risk more than others.
