Suh doubled his sacks from four in 2011 to eight a season ago, but since tallying 66 tackles as a rookie Suh has only 71 total in the two years since. The fourth-year pro is still very much a disruptive force on the gridiron, but in fantasy circles his name carries more value than his statistical production does. Suh is still a rock-solid starter in DT-required IDP leagues, but even then given the pick it takes to get him, you're usually drafting much closer to Suh's ceiling than his floor.
