DaQuan Jones - Defensive Tackle
Jones has been fantastic for the Bills the last two seasons, since joining the team. I do have some concerns with his health, as he hasn't been able to get through a season without missing significant playing time. When healthy, he and Ed Oliver form one of the best interior defensive lines in the league. In addition to the health, he's also 32 years old, so that is something to consider as well.
Despite my concerns, I think the Bills need to make Jones a priority due to the limited players currently under contract at the position. His projected value is set at $6.8 million, per spotrac.com. Buffalo has a few other interior defensive linemen they could consider re-signing to fill this need but none of them are of the caliber that Jones is and are more depth pieces than anything.
