Lol. KG finished 2nd in MVP voting that year and wasn't the best player on the team? The Celtics were the worst team in the NBA the year before he showed up, but he wasn't the best player on the team?
Anyone who says Pierce or Allen were ever the best player on the Celtics when they were all together is a fool. It went from being KG's team to Rondo's - and that Rondo part is debateable because when it mattered most(the playoffs) KG was always the best player on the team even in his twilight years(See: 2011 playoff run, 2012 playoff run).
I just fleshed out the reasons for you homie. Believe what you wanna believe, but most people will tell you KG is better than Pat for the reasons I listed. And if you want to get into advanced stats, KG's career Player Effeciency Rating is 2 points higher.
To be fair, in 07' Pierce played less then 50 games they didnt have Ray Allen and no thibs to install his defensive system which Garnett thrived in. They always did fine without KG from 07-11 anyway
