Scott Neidermayer did. he said so. quite frankly, I don't buy this cloak and dagger "well i'm going to SAY this is why, but it's obviously other reasons". for the most part hockey players will say "it wasn't a fit, thanks for the memories." (in Hockey-ese)
ultimately - something I think you are significantly forgetting. New Jersey haemorrhages (or did) money. it didn't matter about how many times they made the playoffs, etc, Medowlands is and has been for a while, 30th in terms of revenue generated. So if there's not a lot of money coming in, you can't pay everyone you want what they feel they are worth.
Do i think some left due to Lou - sure, just like I think a lot of people stayed BECAUSE of Lou. a LOT of players (minus Parise/Scott) generally didn't end up being "amazing" after they left. Meh on Gionta. Seriously, regarding Clarkson? I remember how Holik hit a wall, pretty much the year after he signed his big payday. So maybe instead of Lou "chasing away" people, he was good in not locking anyone down.
but. again. whatever. milage will vary,
