Some NFL teams draft for need, and some draft strictly with an eye on talent. Either way, most teams still have weaknesses on the roster once the draft is complete. Below, Football Outsiders looks at the biggest hole on each NFL roster as of May 5.

Many of the write-ups reference Football Outsiders stats, which are explained here. The most common is DVOA, or defense-adjusted value over average, which compares every play of the NFL season to a league average and adjusts based on situation and opponent.

Right tackle

One tackle spot is set in Buffalo, with Cordy Glenn signing a five-year, $65 million extension this week. But the other tackle spot is a big question mark. The biggest problem is that 2014 second-round pick Cyrus Kouandjio has never developed. The Bills somewhat made up for that failure by finding a passable right tackle, Seantrel Henderson, in the seventh round that same year. But Henderson missed the last five games of last season battling Crohn's disease, and he's likely to miss at least part of the 2016 season trying to get healthy and back to his playing weight. That leaves Jordan Mills, the Chicago Bears castoff who passed Kouandjio on the depth chart to start last December. Mills was not very good with the Bears, which is why they cut him after only two years. Buffalo didn't draft a single lineman this year; the best remaining free-agent tackle is probably Khalif Barnes, who is 34 and started only one game for Oakland last season.

Cornerback

The Dolphins finished 29th in pass defense DVOA, and last season's top three cornerbacks are now elsewhere. But are the new corners any better than the departed ones? Byron Maxwell showed in Philadelphia how stretched he was as a No. 1 corner, with 9.8 yards allowed per pass according to Sports Info Solutions charting (77th out of 83 corners). Second-round pick Xavien Howard probably will start across from Maxwell, but even the most talented cornerbacks tend to struggle as rookies. The nickelback will be Bobby McCain, a 2015 fifth-rounder who allowed 9.7 yards per pass in limited playing time last season. The good news for Miami is that there are some useful cornerbacks available on the market to bolster the depth, including Leon Hall, Jerraud Powers and the underrated Trumaine McBride, who put up league-leading charting stats with the Giants in 2013.
