We talk often about draft risers, players such as Blake Bortles and Greg Robinson who emerge seemingly from nowhere to become potential top-five draft picks.
But what about the flip side of the coin?
Just as Bortles and Robinson used a breakout 2013 season to put themselves in this position, players who began the year on NFL scouts' radars used poor 2013 seasons to play themselves out of it.
The results of this can be seen in the work of B/R's Matt Miller, who put out a first-round mock draft last June and another—his final seven-round mock of the season—last week. Some of the differences in player stocks are amazing.
For the purposes of this list, we will only count players who hurt their stock by playing poorly. Not included will be players such as Baylor running back Lache Seastrunk, who dropped from No. 19 in the June mock to No. 112 in the May mock but enjoyed a fine season in 2013. His drop had more to do with the rise of other running backs and the devaluation of his position in NFL scouting circles.
Other exclusions from this list will be anyone, like Oklahoma cornerback Aaron Colvin, who has dropped because of an injury. Instead, this list will focus on players who did not post the same game tape in 2013 as they did in the season prior—that being the reason they'll slip.
