I believe his knee made him miss the last three games of the season. I don't see any quit in that dude...he did have 1250 yards in 13 games averaging 4.9 YPC.I think he came back too early because of the SB.

We might get lucky with our first pick last year "Penny" 4.3 speed. He can take one to the house at any given time.
