I really hope not.
Regardless of all the garbage other's here spill, outside of our big three Terry was our best player last season. He was a lot like Pietrus/Marquis in that he was far more productive for us then what people give him credit for...and if he goes and we don't get a VERY good replacement we will regret it later.
He was an absolute critical piece for us in the playoffs. Without him it would have been an embarassig 4 game sweep with an average loss margin of probably 15 PPG. There was nobody else on this team who could cover PG with Rondo out, and Terry did a solid job of that all season when he had to.
