There has been some discussion about acquring a fullback for Jim Harbaugh's WCO. Our best choice may already be on the team. What about converting Nate Byham to fullback? He's 270 pounds, a great blocker, has decent hands and speed as a tight end, and played out of the backfield some last year as an H-back. Since our WCO fullback needs to be able to catch passes out of the backfield as well as block, I think he might be a good fit.
As other options, I really like Stanley Havili from USC as a versatile fullback, or maybe the kid from Stanford.
