1. Denzel Mims, WR, NY Jets
The enigma that is Denzel Mims was arguably the biggest talking point coming out of training camp last summer. Most assumed that the former second-round pick was in-line for a sizable role in his second NFL season, especially after flashing at times as a rookie.
But it quickly became apparent that the new coaching staff wasn't nearly as high on him as many others were. He found himself plummeting down the depth chart and was rendered a healthy scratch early in the year.
Injuries eventually forced the Jets to play Mims, but once he stepped on the field, it became very obvious why the coaching staff was so reluctant to play him.
Mims wasn't just an afterthought — he was a complete liability. He finished the year with eight catches on just 23 targets and a whopping four penalties, which given the tiny number of snaps he played is pretty wild.
In fact, he finished with the second-worst target-to-penalty ratio among all NFL wide receivers, and although he didn't play enough snaps to qualify, his 48.7 PFF grade would have easily ranked dead-last among over 120 qualified wide receivers.
Mims was really, really bad last season. He's reportedly been putting in the work this offseason, but he still faces an uphill battle to earn not only a role in the offense but a roster spot this summer.
Joe Douglas has been resistant to cut ties with his underperforming draft picks, as evidenced by this list, but if Mims shows up to camp and disappoints again, he may not have much of a choice.
Few players have more to lose (or gain) than Denzel Mims this summer.
