Knowshon's game against Baltimore was the most impressive game a Broncos RB has had this year.
The will to drive your feet is probably any RB's most important attribute. Knowshon has been showing that drive the last 4 games...he showed it last year before his injury, and it was his primary attribute in college at Georgia.
Knowshon has proven his worth. You can scratch off 'early round RB' from your draft wish list. I'm sure they can find a late round guy to replace Lance Ball.
Moreno, McGahee, and Hillman have what it takes to put the Broncos Offense on their shoulders when necessary.
