Cooper Rush was Prescott's main backup, with former third-overall pick Trey Lance serving as the third-stringer. Lance was the more intriguing prospect of the two, because he's still only 24, and injuries prevented him from getting a real shot as a long-term starter.

The Cowboys clearly want a young arm they can mold behind Prescott, but in what round they will find that arm remains to be seen. Dallas has three picks in the top 100, but did trade away its fourth-rounder for wide receiver Jonathan Mingo at the trade deadline.
