Keston is a defensive lineman who plays with a physical mindset and a steady motor that shows up throughout every snap. On film, he brings consistent effort at the point of attack and looks to stay involved in plays by working through contact rather than waiting for things to come to him.

Against the run, Keston shows solid strength and discipline, holding his gap and staying square when blockers come downhill. He does a good job absorbing contact and fighting to stay balanced, which allows him to remain effective in the interior and help limit running lanes.
