This is true, but has been in each of the prior two seasons. He clearly looks much more comfortable out there now. Regardless of who the competition was, and remember he was throwing to the Cowboys future cuts too, with the exception of Hendershot who played his way onto the team last night. The fact is DiNucci's was making quick decisions, throwing crisp passes, and moving the 4th string offense down the field. He is still a project but shows more potential than Rush or Grier who have basically peaked.
I think Dallas should keep 3 QBs including DiNucci, but if Dak goes down for any length of time, they are in trouble with either Rush or Grier as backup.
