It already is a trainwreck - Boston fans just don't know it yet.
The Celtics just mortgaged their future on three 30+ guys that have never made the NBA Finals. (and in Allen's case, he was lucky to ever see the playoffs). Neither player even so much as led their team to the playoffs in any of the past two years.
Their point guard (Rondo) couldn't win a 3rd grade 3-point shooting contest. Their shooting guard (Allen) couldn't guard my grandmother. Their small forward (Pierce) is an injury prone ballhog who gets destroyed every time he plays against someone superior athletically (See Lebron). They have no center AND ZERO BENCH.
And now, all of a sudden, they're the best team in the East according to some commentators?
Come off it. They might make the playoffs, and may even win their weak division. But after two years of playoff fizzles, they'll be trying to start all over again with what they have left - which is now, of course, nothing.
Danny Ainge got taken to school on this trade.
