The whole idea of Pierce leaving would sadden me greatly, as he's always bled Green. I remember being at the game in 2002 vs the Nets when they came back from 21 down in the 4th (and 25 in the late 3rd), with Pierce atop the scorer's table pounding his chest afterwards in victory.
BTW. I've seen other reports of this on the web, but it's all based on Bob Finnan, so while "sources" are unfounded, so is Bob Finnan. If not, then Danny better not only have a good plan in mind, but execute it successfully too.
