Look obviously there is damage done by the trade, but think about it
If Ainge hadn't done the trade we would have had : Robinson, Daniels, Erden, Harangody as our bench (3/4 of those guys are injured currently)
With the exception of Daniels, who unfortunately had a season ending injury, none of those guys would have been playoff reliable even on their best days.
I highly doubt the Big 3 went from all-stars to nobodies in a month's time.
The same thing happened last year, and yes that's no guarantee, but it's something that has happened before and history tends to repeat itself.
Look I'm extremely pessimistic about what's going on now as well, chemistry looks dead, but:
CELTICS ARE NOT DONE UNTIL THEY ARE ELIMINATED FROM THE PLAYOFFS. Period.
If you're a real Celtics fan you will support them until they either raise Banner 18 this season or watch them lose in the playoffs because that's what real fans do.
The Celtics are a great franchise, and the last thing I want to see is the Celtics fanbase being a bunch of fair weather fans like the Miami Heat or Lakers, have some Celtics pride.
