Since Buffalo Bills running back C.J. Spiller injured his ankle against the Baltimore Ravens in Week Four it's been a constant debate as to whether the Bills should rest him one of these weeks in an effort to get him near 100-percent health.

For the past three games the Bills have declined that option. They've used Spiller only sparingly (20.7-percent of offensive snaps) and his level of effectiveness has gone down dramatically. On Wednesday the Bills acknowledged that the ankle may not be progressing the way they wanted it to. A day later with another practice missed they confirmed that line of thinking once again.

"He doesn't feel as good in my opinion -- he might say it -- but as far as how he's looked" head coach Doug Marrone said Thursday.

Even the optimistic Spiller who had told reporters a day ago that his ankle felt "ten times better" conceded that he wasn't his normal self.

"Everybody understands you can see it on tape" he said. "A big part of my game is my quickness and my speed and I'm just not getting that explosion that acceleration that I want. I mean I'm able to run but not like I'm capable of."

Now with only one day of practice left before the Bills take on the New Orleans Saints Buffalo is seriously contemplating whether or not to rest Spiller for a game.

"He wants to go but we've got to make a decision" Marrone said. "A tough decision."

While Spiller said he was able to do some of the inidividual drills without a limp today he admitted that he'll understand why he might sit out this week if that's what the team elects to do.
