I really don't like it when people say athletes are silly when they sit out in these situations because they get paid to play a sport.
These athletes, especially in the case of Jimmy Butler, are probably more dedicated to their craft than most fans are to theirs. Butler's diet, sleeping habits, workout routine, etc. go far beyond a normal 8-10 hour a day, 6 day a week type job. This is a life-style.
If he prefers to go elsewhere, and can use the leverage he does have to get there, who are we to question the decisions of his life? Who are we to denigrate his decisions because his craft is a game, or entertainment.
It stinks for the Wolves. It also stinks for NBA fans that might want to see Butler play. But this decision could mean a 50-100 million dollar difference in his next contract. That doesn't include the marketing bonuses that come from playing in certain markets or on a contending team. If he tore his achilles next game, he could miss all of that.
I respect a man that takes strong action, even if he might get maligned for it. It is definitely in his best interest.
Some might say, "But I don't respect a man that doesn't fulfill his contract." That is true, but then again, if he signed a contract understanding the fines that would come his way if he didn't fulfill that contract, then I'd argue he can still be a man of his word by paying the fines while he sits out and asks for a trade.
