Akiem Hicks
Of the four defensive tackles on this list, Akiem Hicks is currently the only one that the Buffalo Bills would have to trade for. The veteran tackle with the Chicago Bears was granted permission to seek a trade at the beginning of the offseason however nothing has been completed yet.
While the Bills are close in terms of cap space to take on the $12 million cap hit Hicks has this season, the team would likely be more interested if he were released and they could sign him to a new deal.
Akiem Hicks has spent the past five seasons with the Chicago Bears and has played some of his best football. He is a defensive tackle that not only can stop the run but provide a little more pass rush than someone like Star Lotulelei. Hicks has had seven or more sacks in three of his five seasons with the Bears.
The combination of Lotulelei, who can be used on clear run downs, and Hicks, who can contribute both ways, could complement each other well and help this defense.
