I haven’t seen Flowers play, but I doubt he is even in the top 250 NFL draft prospects, or top 20 QB prospects. He is likely going to be an undrafted free agent. My thoughts are that if Allen or Mayfield fall to #11, why not take the highest rated QB on the board? Tannehill might or might not recover, and Cutler, Moore and Fales need to retire or be cut. Very few late rounders, or UDFA quarterbacks make the roster or end up at best on practice squads like Brandon Doughty.
I just googled Flowers, and he is listed at 5’10” 1/4....that’s going to make it tough.
