One of the best quarterbacks in NFL history, Drew Brees is listed ahead of Tom Brady in the free agency rankings pages because he played much better than his future Hall of Fame counterpart in 2019. Granted, Brees had a better supporting cast, but the disparity between the two was vast.

Joe Thuney has developed quite well since being a third-round pick in the 2016 NFL Draft. He has become an elite pass protector. Thuney can improve in run blocking, but he still deserves a massive contract.

Brandon Scherff is a very talented guard, but he's had trouble staying healthy. He's missed 13 games over the past two seasons, so he comes with huge risk with his massive reward.

Austin Hooper is a highly athletic tight end who has improved exponentially in each of his four NFL seasons. He won't even turn 26 until October, so the sky is the limit for him.

Danny Trevathan got hurt during the season, but it didn't matter very much because Nick Kwiatkoski stepped in and played on a high level. He'll be entering just his fifth year in the league, so there's definitely reason to believe he could continue to improve.

Graham Glasgow improved markedly in 2019, becoming a stout blocker for the Lions' interior offensive line. Glasgow can play both center and guard very well, so he'll be highly sought after on the open market.

Taysom Hill looked like just a gadget player a couple of years ago, but he was fantastic in the previous preseason, showing the ability that he could one day become New Orleans' starting quarterback.

Maliek Collins puts good pressure on opposing quarterbacks in the interior of the trenches. He'll be just 25 in April, so there's a chance he'll make a big leap in production.

Minnesota's secondary struggled in 2019, but don't look at Mackensie Alexander, who did well in the slot once again.

Carl Nassib is just a mediocre pass rusher, but he's been excellent in run support. Nassib turns 27 in April, so he could improve his pass-rushing ability.

Breshad Perriman had been a major bust throughout his career, but he caught fire late in 2019, finally emerging as a the dynamic threat the Ravens thought they were getting when they chose him in the opening round of the 2015 NFL Draft.
