Why are the Chiefs using Dexter McCluster like is our only weapon?
I believe the answers are that Haley does not trust Cassel enough to make those throws knowing that our offensive line won't prevent Cassel from being pressured, and they are calling safe plays in fear of turning the ball over.
Eventually you will see more passes going to the receivers, but only after the Chiefs realize that we can win throwing 3 yard passes to the Running backs, and dumping the ball of to the TE a yard short of the stick on 3rd down.
This team will change once we get Baldwin, Bowe and Breaston are realized. That already started in the second quarter last week.
