The NFL draft stock market is always open for business, and even eight weeks into the season, there have been plenty of surprises and disappointments. For some players, it's about meeting or exceeding lofty expectations, while others simply come from out of the shadows to emerge as legitimate prospects. The draft process is lengthy, and there's still plenty of season to be played, but here are the players who have helped or hurt their chances at the halfway point in the season.
DL Maurice Hurst, Michigan
Hurst has dominated as a part-time player over the past three years, but this season, he's excelling in more of a full-time role. He played only 47.4 percent of Michigan's snaps in 2015 and 44.2 percent last season, when he was arguably Michigan's most disruptive defensive lineman in a group loaded with NFL talent. This season, Hurst is playing 78.8 percent of the snaps, and he's the nation's No. 1-graded interior defensive lineman at 96.0 overall, including No. 1 rankings as a pass-rusher (92.0) and against the run (93.3). Hurst has disruptive, three-down potential at the next level, and he's on track to be the first interior defensive lineman off the board in the 2018 NFL draft.
