The physical differences are noticeable between free agent acquisition Le’Ron McClain (Chiefs, 6-0, 260) and last year’s starting FB Jacob Hester (5-11, 235). “He is a big mean guy,” RB Ryan Mathews said of McCLain. “He is going to be able to move guys out of the way and open up the holes. He is very athletic. He can also catch the ball out of the backfield, and he can block.”
