Keller plays with confidence plugging the middle, and uses his nice frame to get the ball carrier down with relative ease. At 6’2″ and 220 pounds he has good size, and an above average football IQ gets him in the right spots a lot times. It’s not surprise to hear him leading his region in tackles, that attribute is consistent on film. Keller has solid straight-line speed, but doesn’t change directions too well, and can potentially end up in poor angles where he is making an arm tackle. Cannot argue against his production, Keller has quality upside given his frame and general athleticism. He’s tough, takes on blocks with little fear, and this year he is getting better leverage.
