ESPN.com is ranking NFL players and counting them down (follow on Twitter @ESPNNFL) from No. 100 to No. 1 on both offense and defense, 10 per day for 10 days. The top 10 on both sides of the ball will be revealed Friday, Aug. 29.
The rankings were based off votes from 90 ESPN NFL experts.
It's a bit of a drop for Spiller, who came in at No. 58 last season. His total yards dropped from 1,703 in 2012 to 1,118 last season, although part of that was tied to his early-season ankle injury.
