There may not be many, but the they were high first rounders. Alex Smith, Eli Manning, Joe Flacco (for a period of time), Matt Ryan, Cam Newton. These are guys who did pretty much nothing on their rookie contracts, got big extensions, and then clearly blossomed into top-of-the-leaderboards type QBs. It's not all first rounders, not even most. But players get picked in the first round for a reason: longterm potential. The team saw the potential for this to happen.
