Next position up for debate is the fullback position. If you haven't voted in the poll for running backs, you can go here to do that (there wasn't a poll originally due to some technical difficulties). If we're all caught up, let's take a look at the bruisers who pave the way for the running backs and catch the occasional pass out of the backfield.
The Raiders only Pro Bowl player the past couple seasons. He continues to be the most versatile fullback and all-around weapon out of the backfield in the league. And yet, he is usually underutilized. Aside from his usual blocking duties, he caught 37 passes for 265 yards and one touchdown and had 21 carries for 85 yards.
He is seen as the more traditional blocking fullback. He can do a decent bit of catching out of the backfield but can't be counted on to carry the ball. He had 5 catches for 18 yards and 2 touchdowns and carried the ball twice for zero yards.
