This is a blatantly "glass-half-empty" post, which completely ignores that Ginobili had already regressed last season and the team still got to game 7 of the Finals. Parker is in his prime and will, more than likely, retain his skills (I don't see him dropping off a cliff). Timmy is in incredible shape and has progressed in his last couple of seasons. Even if he does regress slightly, he's still better than most bigs in the post. It's his lack of athleticism and his intelligence on how to overcome it that has contributed to his renaissance.
Why do you so badly want to blow the team up when they only needed a couple of tweaks here or there to win it all? You cannot deny that one rebound, one better pass, one more made basket would have made all the difference. Why destroy half the team for an UNKNOWN variable, when you already have is pretty damn good?
Don't be a cynical Spurfan, they're not done winning basketball games yet.
