WTF did Jerry Porter change his number from 84 to 81? Is Oakland planning on having a WR with #84 come aboard and Jerry was O.K. with it? or is there a team he may be going to that already has a #84 thus the change? Weird thing,never heard it before,especially when it is done by a veteran...But of course this is the Raiders and a WR core of disorderly and selfish players,so nothing is really surprising,but this is strange.
