You would have never gotten those three QBs in my 2QB Keeper. Maybe because your league is small at only 10 teams. Imagine being in a 12 team league or bigger. There are only 32 starting QBs. Every team needs two starters and a back up not just for injuries but also for the two bye weeks. So(12 team league) you need 36 starting QBs but because there are only 32 NFL teams that leaves four fantasy teams pretty screwed.
I would 100% make sure a QB is my first pick. It is way easier to pick up a WR or RB of the wire than a QB during the season.
