Dylan has great potential and is already a great intermediate passer. It is the deeper throws and long balls which he is not adept at throwing from what we've seen thus far. It seemed like most of his deep throws last year would be floaters the WR would come back to, not bombs that hit them in stride.
For his running, he's not the most athletic guy but could pick his spots better on when to run and slide. I don't think it's as much of a liability as some make it out to be.
I'm happy he's our QB and think he can improve as he's just a SO.
