There is game tape this year(New England game) and last year(final 6 games) that proves Parker can be dominate. He has definitely been a disappointment thus far, but we have half the season left. Remember a month ago we were the worst team in the NFL. We had no running games, no defense, and the worst oline, and boy has that changed, so its never to late to turn it around. I wish they would be proactive in trying to get him healthy if that is the major problem right now. I would not be opposed to leaving him behind this week like we did to Jay in week 1. Let him rest the hamstring and try to motivate him going forward.
