They had a large series of bets come from the Michigan area and dropped the odds from 8-1 to 2-1. This was reported on Gambling911. Interesting, it's not a state secret that Harbaugh probably won't be with the 49ers next season. The key is if Harbaugh leaves for a college job the 49ers receive no compensation. If a pro team wants him they will have to fork over draft picks as he is still under contract for another year. I don't know why you would leave the NFL to return to college especially since Harbaugh has been very successful at the pro level.
