Chum1's not really wrong. I think oscar can sustain a program that gets to the tournament 30-40% of the time, which is probably above average for even a P5 coach, especially when you take out coaches from non-blue bloods.
If you knew nothing about Brad, (including his record), you could safely assume he would be worse than oscar. I've long subscribed to the thought that a complete unknown is better than a shitty "known", but in oscar's case he is more average than shitty which creates an interesting dilemma. In a way, keeping oscar is a ballsy unconventional way of thinking that is sort of compelling.
