Grover Stewart

While DeForest Buckner gets all the attention in the middle of the Colts' defensive line, Stewart thrived in his shadow last year, racking up career highs with 70 tackles and four sacks. A fourth-round pick out of Albany State in 2017, Stewart needed time to add NFL-level skills to his power and athleticism, but teaming with Buckner the last three years took his development to another level and allowed him to come into his own, and with defensive coordinator Gus Bradley sticking around another season, there won't be any big scheme changes that might change his role.

Stewert is primarily a run suffer as a starting nose tackle. The fifth-year defensive tackle had 43 tackles and 23 stops last season.
