It may be average, however there are circumstances that could have effected that number. ( QB play, i.e., placement of passes, type of routes run, along with he's not a big imposing receiver, so maybe isn't as effective at breaking tackles, etc.) Having 4.37 speed, plus as a punt returner he had 3 TD's, and 2 called back in his college career, shows he is elusive. He creates separation right off the line. Even though the college stat you noted says he's average, the potential is definitely in his favor to change that at the next level.
