This guy was almost drummed outta the NFL last preseason because he looked so awful. He wound up having a mediocre season (3700 yards/21 TD's/13 int's....plus 320 yards rushing w/2 TD's), but claims to have played with a lot of pain, with a partially torn ligament in his throwing hand which he actually acquired in the 2016 season, but was finally repaired in off season.
He is only 2 years removed from a 4400/35 season which also included 310 rushing w/2 TD's. Those are QB1 #'s. Camp reports are raving (see ESPN story link below), and he arguably has the best receiving corps of his career with Cole, Lee, Chark, Moncrief, and Westbrook.....not to mention ASJ as TE. That's a sweet looking group.
Best of all, he is often going undrafted right now in 12 team redrafts, with guys like Manning, Trubisky, and Dak going before him. Heck, even Tyrod Taylor is beling drafted ahead of him.....and we all know that he might not be playing long before Mayfield sees the field. (BTW, I highly recommend grabbing Mayfield if you have room to stash him.....could be this years Watson.)
Yes, the potential downside is that the Jags have a legit defense and good running game with Fornette, Yeldon, and Grant....which could lead to negative game scripts. However, for a guy that has done it before and costs you nothing, isn't he exactly what we as drafters look for? I definitely ain't pimping him.....in fact, I have never cared much about him. But, instead of trying to figure out which JAG WR to draft, woudn't the smart money be on the free guy chunking them the rock?
