Williams is the type of player you find on 13 and 3 teams. In addition to being an efficient running back, He can return punts, kickoffs, can tackle, is a leader on the field and off, is faster then Gates, is not afraid to run inside the tackles like Gates was last year (Result, Gates, no playing time).
How many yards would Gates have gained on those hopeless third down and forever draw plays that Williams was asked to run over and over?
Fortunately, Levy and the coaching staff know an excellent player when they see one. Unfortunately, not too many posters on this board do.
Sorry folks if you disagree with me but this was a no brainer.
