I am just glad they made the decision in May (or sooner, really) and he has every chance to get settled in over the next several months. I feared an "open competition" which typically seems to just water down anyone's chances to take a job and be ready because reps are being split 2 or 3 different ways. Give Corbett every 1st team rep possible.
Joint practices with DAL and LVR will be important for Corbett. And internal team scrimmages (assuming, as usual, that the starting OL does not play in preseason- though maybe the RG candidates do).
