The Bills want to give Fred Jackson a contract extension, but C.J. Spiller hopes and plans to start at running back. If Spiller isn't named Buffalo's starter, things could get rough in Northern New York. Spiller was No. 1 on the team's depth chart in the second half of the 2011 season after Jackson's season-ending leg injury. The ninth overall pick in the 2010 draft finished the year with 561 yards rushing, and an average of 5.2 yards per carry.
