Some NFL teams go after positions of need and draft a second-round star, as the Dolphins did with Jarvis Landry. Others simply have the good fortune of a fourth-round insurance pick blossoming into a franchise QB, like the Redskins with Kirk Cousins.
Here are the biggest draft steals of the past five years, with Steve Muench tackling the AFC teams and Kevin Weidl evaluating the NFC teams.
Georgia OT Cordy Glenn: 2012 second round (41st overall)
There's a reason teams value left tackles so much. Finding one with the length and foot speed to match up with the best edge rushers in the league, as well as the size and power to create seams in the running game, outside the first round is no easy task. As such, the Bills did well to land Glenn nine picks into the second round. He stepped into the left tackle spot in Week 9 of his rookie season, and he has started there every game since. He made great strides in pass protection last year, and he has continued to progress to the point that he is one of the best pass-blockers in the league, so it's no surprise the Bills placed the franchise tag on him.
