Not sure about your "connections" to OBD, but respectfully, but I'm really starting to question your football knowledge based on your recent posts.
Before his groin injury, Fred was averaging 4.3 ypc -- just a scooch below his 4.4 career average. He also had 33 catches at a 7.9 ypc (vs an 8.2 career average). Coming back from the injury too soon (after missing only two games) was the problem, IMO, as he never had the same burst.
Freddie's no doubt on the downside of a great career. But to say he should retire is just plain dumb,,,
