Fans have the right to root for different things.
Some fans desperately want this team to bring back the big three and add pieces to make another run.
Other fans desperately want this team to tank to the bottom of the lottery, winning 25 games per season in the hopes that someday we'll be good enough to consistently reach the Eastern Conference Finals again.
Still other fans think that this franchise stands for even more than its 17 championships, and take pride in our history, tradition, and loyalty. Those are the fans who are glad that Larry and McHale retired in green, and who appreciated the basketball those guys played while delaying our glorious 20 year rebuild.
I say, live and let live. No group of fans has the monopoly on being right. If folks want to trade Paul Pierce, good for them. If they want to cheer a career Celtic when his number is retired, that's cool too.
