Fantasy football mavens across the country spent a good chunk of the 2013 NFL season cursing Buffalo's C.J. Spiller. Coming off an explosive 2012 season when he rushed for 1,244 yards (with a whopping average of six yards per carry) and caught 43 passes for 459 yards while scoring a combined eight touchdowns, Spiller was a consensus high first-round pick in the world of make-believe football. And then, faster than you can say Aaron Maybin, Spiller turned out to be a first-round bust. He suffered a high ankle sprain in Week 4 against Baltimore, and spent the rest of the season in pain, unable to play anywhere close to the level his fantasy owners expected, or, more importantly, the Bills hoped for and needed. "It was very frustrating," Spiller said the other day following a practice in which he was operating 100 percent pain-free, just as he has all summer. "I'm a very competitive person and I want to be able to be out there to help my team win. After I got hurt, I was anywhere from 50 to 60 percent. I was never myself." It showed. Despite the injury, Spiller managed to gut it out for 933 yards rushing, but caught only 33 passes for 185 yards and scored a mere two touchdowns in 15 games. He had only four 100-yard games, and in five games he rushed for a shake-your-head 23 yards or fewer.
