If you would have read my post, you would have seen that I had mentioned Tyrod. Still it's not the norm to find a worthwhile QB in the 6th round. I stand by my opinion that if you want a decent to good QB, that selection should happen before the end of the 4th round.
Off the top of my head, I can only think of Adalius Thomas selected in the 6th that went onto become a starter for us. In addition, I can name numerous undrafted players that were starters for us over the years. In 2016 alone we had Orr & McClellan.
