The Green Bay Packers will most likely keep three halfbacks on the final 53-man roster, setting up a training camp battle for the No. 3 spot behind Eddie Lacy and James Starks between undrafted rookie John Crockett and practice-squad holdover Rajion Neal.
Any chance for the Packers to carry four fullbacks on the final roster is negated by veteran fullback John Kuhn and rookie Aaron Ripkowski vying for two total spots. Considering that third-string running back DuJuan Harris only played 51 snaps (of 1,018 total running back snaps) in 2014, per Pro Football Focus, a fourth back wouldn't get much use in the rotation.
