I know that we are going to the second round going against the Cavaliers, but I always like to think ahead. How could this team improve?
To answer that we have to look at our weakness: age. I think the person who's age is affecting him most is Ray Allen, he is older than the other two and his age seems to be showing quite a bit.
With Rondo and Powe we have two young players that can contribute for along time (especially Rondo)
We need someone that can run in the backcourt with Rondo, that likes to drive and cut and can be Rondo's running mate.
Another way to improve in Rondo himself, he needs to step up and take control of this team, he is a special player and his ball-handling ability and play making ability, coupled with Garnett, Pierce and Allen gives him a lot more opportunity.
Also Sam Cassell isn't what he used to be, so we need another backup point, possibly Gabe Pruitt.
That's about all that I see, but overall I don't see Ray Allen being all that affective next year.
