I hate to hijack but Kevin Smith's *almost* record yardage came against the likes of Louisiana Lafayette, Tulsa, UAB, Southern Mississippi, etc. And it required a record number of carries to get there.
Add in the fact that he was tackled for a loss/stopped for no gain almost 90 times his junior year - that shows lack of patience.
And let's not forget about Jerome Felton either. he could be the goalline back, plus he's not a bad receiver and we shouldn't discount his ability to run the ball. The Lions carrying 2 backs, to me, says Felton will get some carries.
89 times, but who's counting?

Again, I think far too much is made about the impact fullbacks and "big" goal line specialists can have. Every fantasy season we hear these discussions and yet, with VERY FEW exceptions, they don't materialize - at least in circumstances where the lead back doesn't get more short yardage touches and TDs anyway.
How many of those few times have been Denver RBs?
Great question, and the answer is "not many."Here are Denver's leading goal line rushers (5 yards and in) over the 2002-2007 period:

As you can see, except for 2003 when Mike Anderson got about half the goal line carries despite being 3rd on the team in rushing attempts, Shanny has pretty much given the money touches to his main back.
