Would Dameon Pierce be better utilized as a Fullback?

Devin Singletary has made his case to be our RB1 for at least the next two seasons and I don't know if Pierce will be able to get that job back but the guy runs with power and purpose. We know he made major improvements in pass blocking this year. He can contribute on special teams and really carve out a role for himself in a forgotten skill position. Should he be moved to FB or should he remain with the RBs?
