Let's check in on a few somewhat off-the-radar prospects who'd be logical fits in Buffalo, seem to have first-round value and should be available when the Bills go on the clock in the first round of the 2018 NFL Draft.
Ogbonnia Okoronkwo, edge-rusher, Oklahoma
Okoronkwo is probably the most well-known player on this list, and most of that is due to success of the Oklahoma program during his time with the Sooners. At around 6-foot-1 and 240 pounds, Okoronkwo doesn't have prototypical 4-3 defensive end size. However, Sean McDermott tapped into every ounce of potential in the similarly sized Mario Addison in Carolina. Now he's the Panthers most productive pass-rusher who carries out a handful of tasks each game, including blitzing inside and sinking into coverage. The Oklahoma star would add more juice to Buffalo's outside pass-rush.
Dorian O'Daniel, outside linebacker, Clemson
Another versatile linebacker, O'Daniel is more of the off-ball/coverage type than Okoronkwo. The senior (something McDermott certainly liked in the 2017 draft) currently has 58 tackles, 8.5 tackles for loss, 5.0 sacks, two interceptions, two touchdowns, and two pass breakups this season for Clemson. In 2016, the multitalented defender had 54 tackles, 10 tackles for loss, 2.5 sacks and one pick. He typically aligns well outside the framing of the defensive line to deal with outside pitches, bubble screens to receivers and anything else near the perimeter. Clearly though, he's capable of making plays that are more centrally located. He'd fit nicely as a replacement for Lorenzo Alexander at strongside linebacker for the Bills.
Derrick Nnadi, defensive tackle, Florida State
Nnadi was the No. 8 overall defensive tackle recruit in the high school class of 2014, according to 247Sports. Since then, he's been a standout on the interior of Florida State's defensive line. At 6-foot-1 and 312 pounds, Nnadi is a load at his defensive tackle spot and is rarely moved off the ball due to immense strength and anchoring ability. He also has consistently shown refined hand use to dispatch offensive linemen to make plays against the run. Nnadi is fresh off his best game of the season as a pass-rusher against Syracuse. He'd be a logical player to add to Buffalo's defensive tackle spot.
Will Hernandez, guard, UTEP
Hernandez isn't a household name... yet. The UTEP stud is a rock in pass-protection and rarely gets moved as a run-blocker. He's tremendous at locating and contacting linebackers at the second level. At 6-foot-3 and 330 pounds, Hernandez certainly has NFL size for the guard position. With Richie Incognito nearing the end of his career and Buffalo's right guard spot in the state of flux, Hernandez could potentially be a welcome addition in the interior of the offensive line.
Kameron Kelly, cornerback, San Diego State
I can't get a feel for where Kelly will be valued by NFL evaluators, but I've loved what I've seen on film from the San Diego State secondary member. He's listed at 6-foot-2 and 200 pounds, so his height fits what Buffalo wants out of its cornerbacks. He's made eight interceptions in his last three seasons with the Aztecs and has defended 12 other passes. He's a twitchy, super-aggressive cornerback who's also not afraid to lay the lumber against the run, something McDermott definitely likes.
