I am out of the state, so not exposed to all the commentary, but I think the general consensus is that one of the big things keeping him away from BYU is that he'd be unlikely to start over Hall. Personally, I would like Dart with us for a number of reasons, one of which is that I have been burned by QB injuries too many times, and I worry about Jaren- not because he's especially fragile, necessarily, but because he's a running QB who is one injury away.
Of course, it may just be that he's so hard to identify, since he looks like everybody else 😁.
