C.J. Spiller an improved pass-blocker

Bills HC Chan Gailey praised RB C.J. Spiller for his pass-blocking ability.  That was the biggest knock against him during his 2010 rookie campaign, and it may have limited his playing time early last season too.  “He can do a lot of things blocking,” Gailey said. “He’s gotten better at his blocking from the previous year.”  Pro Football Focus actually graded Spiller as the 5th-best blocking RB in the league last year, although teammate Fred Jackson finished 1st.  Both guys have emerged as well-rounded RBs who can play all over the field.  Buffalo is looking to get Spiller and Fred Jax on the field together in 2012.  But it's tough to imagine either guy getting enough touches to be anything more than a RB2 in fantasy.
