Yeah, blow up a team that has a realistic shot at the title this year... 
Define "realistic"?
I think as currently constructed, C's are a top 4 team in the East. Not top 2 - top 4.
Rondo is at his prime and is a top-5 player in the league.
KG and Pierce are very effective - but no where near their primes. Both are well over 35.
Green is coming off an injury that cost him an entire season and was a decent-but-nowhere-near-all-star caliber player before the injury.
Avery Brady is a promising young player . . . but he's not going to be the next Joe Dumars.
Our bench guys are solid and talented.
What does that add up to? A couple of 45-52 win seasons and 2nd round exits, with an occasional foray into the ECF. Until KG retires . . . and PP retires . . . without preparation and we become a perennial 41-50 win/5th-6th seed, stuck in the middle. Not good enough to win it all, but too good to strike it rich in the lottery.
This franchise is about CHAMPIONSHIPS, not playoff appearances. We got our last championship by putting ourselves into position to trade for two Hall-of-Famers, which we were only able to do because we had a lottery pick (Jeff Green) and other players recently drafted in the lottery (Telfair, Jefferson) and other 1st round drafted players to send them.
I don't want us to be in the Pacers//jazz mold of "teams-that-were-never-good-enough-to-get-over-the-hump."
We need to get to 18 banners before the Fakers!!!!!!!!!
