The Tennessee Titans are very lucky that they have Jeffrey Simmons on their side. 

He is a force at defensive tackle who is very hard to stop. He had the highest DT impact rating last season per Pro Football Impact, with a 99.73. Some of the players behind him include Cameron Heyward (92.59), Chris Jones (88.37), Kobie Turner (86.50) and Quinnen Williams (86.39).
