The ruthlessness of it still stings me a bit, too. No happily ever after in NFL, NBA, what-have-you. It's a lesson that kind of hangs there, even this year, regarding QB trades and decisions. Despite whatever rah-rah stuff I might say about Niners, I fully anticipate some upcoming decision or trade that might be discomfiting. Warriors, too.
But one of the biggest nuts to crack is when team can no longer afford somebody because of their accomplishments. It's easy to resent Brady as one of those upper middle-class San Mateo guys if you come from blue-collar background. A lot of your gossipy peeps resent his perfect marriage to perfect model and perfect kids etc etc. But the guy structured multiple pay cuts to keep the Patriots from falling into that trap. Some people might hate them for that, or grumble that his model wife makes more money, but he did something that to me, adds some lustre to his perceived greatness and actually rewarded fans for a while anyway. That was real money and in the world of pay and ego, it was notable.
