NCAA bars Bret Bielema from crashing Michigan's IMG practices

Bret Bielema is a little bit crazy, and nothing showed that more than this tweet from Wednesday.

Bielema had joked that he was going to crash Michigan's open practice at the IMG Academy in Florida on Thursday. In fact, a lot of people were exactly to see the reaction if Bielema and Michigan coach Jim Harbaugh were to come face to face. However, we won't get to see such a showdown, as the NCAA decided to step in and remind Bielema of these things called "rules".

Such a shame, but probably for the better than Bielema will stay focused on his own team instead of crashing Michigan's practice.
