Honestly, I haven't read this whole thread, so if someone has said this already, please forgive me. But, Paul Pierce, thus far, playing his whole career for one team is HUGE in my opinion. I know the so-called experts don't factor stuff like that in. But, in my book, there is nothing better and more hall of fame worthy than that.
Furthermore, didn't Vince quit on his team in Toronto? Paul never did that. Pierce also led a pathetic C's team to the eastern conference finals (something Vince couldn't do when he was manning up alone in Canada).
But, on the whole, I think you're right. Their stats are comparable. But the biggest difference is that Pierce won his championship, while he was the captain and still "the man," after years of enduring and toughing it out in Boston, when he could have demanded a trade (Vince style). That's what made Paul's title, as we all know, so sweet. Vince is just hopping ship trying to not be known like his cousin.
