The NFL has become so specialized, particularly on defense, that players are increasingly difficult to categorize. Seeking fresh perspective on the 2011 draft, I reclassified the 254 players chosen into 20 positional categories, based largely on how teams plan to use them. The process was imperfect because teams view players differently, and some players transcend easy categorization. But patterns that emerged were helpful in bringing the big picture into clearer focus.
Overall, this draft featured 37 cornerbacks; 28 wide receivers; 24 running backs; 21 interior offensive linemen; 20 offensive tackles; 16 safeties; 13 tight ends; 12 quarterbacks; 12 4-3 weakside linebackers; 11 4-3 defensive tackles; 10 4-3 defensive ends; 10 3-4 outside linebackers; eight five-technique defensive ends; seven 3-4 inside linebackers; seven fullbacks; six 4-3 middle linebackers; four 4-3 strongside linebackers; four nose tackles; and two specialists. Two defensive linemen -- Kansas City's Allen Bailey and Baltimore's Pernell McPhee -- qualified as nickel pass-rushers.
