IMO, Brown has been listening to the negative recruiting that has undoubtedly been going on. What have the Turds and everyone else been saying about Mario? "He runs the ball 70% of the time"; He wasted Justin Herbert"; and anything else they're propagating. So despite having TVD, Garcia, Brown, and now "his boy" Rashada, he STILL wants to see what the offense looks like!
For the record, I'm not mad at Brown and he will still, in all likelihood, end up a Cane, but he has to make sure he separates the truth from just another narrative.
