The Wisconsin job never officially hit the market as I recall. Bo Ryan stepped down mid-season and Gard took over and did well after initially stumbling. Gard finished the year 11-2 or something and made the Sweet Sixteen, good enough to give him the reins. Now, if the argument is that Bennett could have come in and said "I want the job" and didn't, that's tough to say. If that job went public, I'm sure he would have been contacted and he would probably have gone. Seeing that the program is in good hands (Gard is likely going to win the conference title this year), he could definitely see that the job will not open for a long time.
I'm honestly not sure how much Bennett wants to leave, but Wisconsin isn't going to come calling anytime soon barring scandal or a collapse, neither of which really happens there.
