INDIANAPOLIS -- Justin Blackmon's credentials make him a high first-round prospect in the 2012 NFL draft.
How high? Would the St. Louis Rams take him second overall?
History suggests Blackmon doesn't fit the physical profile for wide receivers selected among the top three overall choices. That feeds into the thinking St. Louis might trade back from the No. 2 overall selection before taking the talented wideout from Oklahoma State.
NFL scouting combine officials measured Blackmon at 6 feet and seven-eighths of an inch. Blackmon weighed 207 pounds. The height will round to 6-foot-1, plenty tall to play wide receiver in the NFL, but quite a bit shorter than the wideouts teams have selected among the top three overall choices since 1985: Calvin Johnson, Braylon Edwards, Larry Fitzgerald, Charles Rogers, Andre Johnson and Keyshawn Johnson.
Four additional receivers come under consideration when we expand the range to players drafted among the top five overall choices. A.J. Green (6-4), Peter Warrick (5-11), Michael Westbrook (6-3) and Desmond Howard (5-10) were selected fourth overall since 1985.
Height isn't everything in a wide receiver, but those drafted earliest have generally been taller and heavier than Blackmon. Will that apply to Blackmon as well? On a side note, he isn't running at the combine after suffering a hamstring injury last week.
