Then why does he have to lie about it (it's the lying that hurts!)? Why does he use his family as an excuse to move on to a situation better suited to his goal of winning another ring? Why lie to the team he's leaving and why lie in the press?
Sure, it sounds a lot better to say: "I'm leaving to spend more time with my family" than to say, "I don't think my current team has a shot at a ring, so I want to go someplace that does". Except, when the former ends up being a flat out lie.
Seriously, if Fisher is such a devoted family man would he really have grown tired of spending time with his family after only 2 months, relocate 1300 miles away and be on the road from February - June? If his kids really needed him, wouldn't he have stayed with them in Los Angeles?
It's the lying and using his kids as an excuse for reneging on his contract that makes him a scumbag - that and the fact that he once, make that twice, wore the piss and purple.
