Biggest Post-Draft Weakness: Tight end
The Bills immediately hit on some of their biggest needs in the draft with wide receiver Zay Jones, right tackle Dion Dawkins, and cornerback Tre'Davious White. They did not, however, select a tight end in what was a rich draft for the position. Charles Clay has been serviceable for the team the last two years, but nowhere near worth the sixth-highest average salary at his position. Clay led the team in targets in 2016 due to Sammy Watkins' injury, but he also averaged a career-low 9.7 yards per catch, and his 36.8 receiving yards per game were his lowest since 2012. The Bills are paying above-market value for below-average play at the tight end position, and that will likely continue through 2017.
Notable Undrafted Free Agents: If the Bills wanted to find a receiving tight end this way, then it will have to be Tennessee's Jason Croom. He has experience at wide receiver, but needs to work on his blocking and will have to shake his history with injuries and dropped passes. Otherwise, the Bills picked up Louisville tight end Keith Towbridge, but he is more of a blocker (21 career catches).
Biggest Post-Draft Weakness: Guard
After years of using high draft picks on wide receivers and offensive tackles in recent seasons, Miami targeted linebackers in this year's draft. With that unit addressed, Miami's offensive line remains the biggest area of concern, particularly at guard where the team hasn't invested first-round picks. Veteran Jermon Bushrod struggled in his move to right guard last season, and Miami waited until the fifth round to take Utah guard Isaac Asiata. A healthy return of center Mike Pouncey and a full-time move to left tackle for Laremy Tunsil should help, but Miami's interior could still struggle. That would be a problem for quarterback Ryan Tannehill, who has always done a below-average job of handling pass pressure. Last season, Tannehill ranked just 20th in QBR (21.2) while pressured.
Notable Undrafted Free Agents: Michigan running back De'Veon Smith was signed, but he projects as a poor man's Jay Ajayi, lacking the receiving talent and speed to be a productive back. Miami signed four wideouts, but the most notable is Mississippi's Damore'ea Stringfellow, who had a career-high 716 receiving yards in 2016. He is a 6-foot-2 receiver who can high-point the ball, and the Dolphins only have four real locks to make the roster at this position in Jarvis Landry, DeVante Parker, Kenny Stills, and Leonte Carroo.
New England Patriots
Biggest Post-Draft Weakness: Offensive Line
Did the rich get richer? The defending Super Bowl champions have strengthened their skill positions with the additions of Brandin Cooks, Mike Gillislee, Rex Burkhead, and Dwayne Allen. They added Kony Ealy to the pass rush and Stephon Gilmore to the secondary. The Patriots only made four selections in the draft, but this was not a team with many pressing needs. (In a previous article, we said that the Patriots' biggest hole was at defensive end, and they drafted two of them.)
If anything looks unimpressive with this roster, it would be the offensive line. Even that is far from a liability, given that Nate Solder is a solid left tackle and the Patriots drafted Antonio Garcia, a potential replacement down the road, in the third round. Right tackle Marcus Cannon looked far improved in his first full season as a starter. The Patriots are still relying on some younger players such as left guard Joe Thuney and right guard Shaq Mason, but offensive line coach Dante Scarnecchia will put the best he can in front of a 40-year-old Tom Brady this season.
Notable Undrafted Free Agents: The Patriots added Northwestern wide receiver Austin Carr, who would be a bit big (6-foot-1) for New England's typical slot receiver preference. Richmond defensive back David Jones led the FCS with nine interceptions in 2015. Defensive end Corey Vereen had 7.0 sacks for Tennessee last season.
New York Jets
Biggest Post-Draft Weakness: Quarterback
Outside of the defensive front seven, the Jets are fairly weak everywhere. However, nothing may present less hope than the most important position of them all: quarterback. While some thought the team might sign veteran Jay Cutler or draft a quarterback high (again), the Jets are rolling with Josh McCown, Bryce Petty, and Christian Hackenberg this year.
If being terrible enough to earn the No. 1 pick in the draft is a goal, then McCown might be the right man for the job. He has recently helped Tampa Bay (2014) and Cleveland (2016) to the top pick in the draft, and his Browns finished No. 2 in draft position in 2015. Petty's 19.4 QBR last season was the lowest among any quarterback with at least 75 action plays. Our QBASE projection system for college quarterbacks has Hackenberg as one of the worst prospects since 1996. So the Jets may already be in the lead in the race to USC's Sam Darnold in the 2018 draft.
Notable Undrafted Free Agents: Gabe Marks was a very productive receiver in Mike Leach's Air Raid system at Washington State, where he caught a Pac-12 record 316 passes. Yes, most were short throws to take advantage of his short-area quickness, and you won't expect to see him go deep much at all. That means he'll project as a Wes Welker or Danny Amendola type in the NFL, but the Jets would be more than satisfied with a Wayne Chrebet or maybe even Jeremy Kerley type of career from Marks. The 2017 Jets are not exactly overflowing with receiving talent, so there is potential here in the preseason for Marks to make the team.
