Spiller spent the first year and a half of his career making Bills management look like fools for using the 9th pick in the 2010 rookie draft to acquire him. However, Fred Jacksonís season-ending leg injury thrust Spiller into the starting lineup and he played far better than anyone could have anticipated over the balance of the season. After a poor performance in his first game as a starter, Spiller accumulated 446 yards rushing, 187 receiving yards and scored five touchdowns over his last six games, hitting double-digit fantasy points four times. That means Spiller has solidified his standing as the Bills running back of the future. What it doesnít mean is that he has earned a huge role in 2012. Jackson was a beast when healthy in 2011 and signed a two-year contract extension in the offseason. The expectation is that he will get the majority of the touches in the Bills backfield but that Spillerís use wonít be as minimal as it was when Jackson was healthy. Consider Spiller a high-end RB4 with upside.
