I don't think this has anything to do with Harvin's production on the field.
And I think that if Harvin was scoring 2 TDs per game, we would still have been tempted to trade him (unless we were winning because of it).
It sounds like Harvin was creating a faction. You get reports of the the pro-Wilson guys, and the guys that were sick of it. And the guys that already won the SB and were dialing it down a bit this year. Harvin is clearly a path of least resistance player. I mentioned that several times when they got him. And it sounds like he was starting to get followers, who might have been sick of the bullsh*t.
Wilson is a driven guy. The extent of which might be an act but it might be borderline OCD. Either way, it sounds like his work habits are stellar and he is a perfectionist. Perfectionists are great when you reap the reward from their work, but they are a pain in the tail to work with. I can see how people might start griping about Wilson being demanding, not accepting "good enough", etc. I can also see people using his lack of production this year against him, pointing out he has no standing to hold people as accountable when he is not producing himself.
Either way, based on what is being reported, it sounds like Harvin was stoking resentment of Wilson in an attempt to get more control of the locker room. OR all the reports are part of a whisper campaign to influence perception of Harvin because they don't want to upset the fans with the trade. Maybe a bit of both.
But what floors me is that a guy that had problems everywhere he went, was seen as a surprise when he started causing problems here.
