I saw an interview with Nelson shortly after he signed the last one. He almost seemed embarrassed when they started talking about money. He was asked if this was a "fair" deal for him, in view of what other WRs had gotten. He went into a long discussion about how they are all paid way too much for what they do, that he had already made an awful lot of money just to play football, so, yes, to do what he does, this was fair. If it was low in eys of others, at least the Packers would have ability to sign team mates, etc.
I think Jordy will always seem like a bargain, because it didn't sound like he would ever have demands.
