Dan Mullen’s success at developing quarterbacks has been well-documented. From Alex Smith to Chris Leak to Tim Tebow to Dak Prescott to Nick Fitzgerald and, most recently, to Kyle Trask, few coaches can boast a track record as good as Mullen’s.
One of the biggest keys to Mullen’s steady stream of elite quarterback play is how seamless the transitions look from one guy to the next. When somebody of Prescott or Leak’s ilk departs, it’s almost assumed that there will be a significant drop-off at the position the following season. Instead, the train usually just keeps chugging down the tracks.
