The recent acquisition of Kevin Garnett by the Celtics looks to be a great move, but will it really be. One fact that i have heard brought up the most is that they have three of the top twenty scorers in the league. Most likely, only one of them will be able to crack the top twenty this year, and possibly another will sneak in.
I have seen many people pick the Celtics as the favorite to win the Eastern Conference, or at the very least win their division and get a top three seeding in the playoffs. Although, I would not be surprised to see this team fail, even if only this year. KG is a very great and selfless player, but the problem I could see is Paul Pierce. He is not used to having another above-average player on his side, and it will take him some time to get used to be able to trust the others on the court. Ray Allen is very good, but he is old and a shadow of what he used to be.
Another major problem for the Celtic's season is the injury problems of Allen and Pierce, Last year, they combined to play a total of about 120 games out of a possible 164, and that total could possibly decrease. They have both been plagued with multiple injuries in recent years.
The final flaw could be the rest of your starting lineup. The projected starters at center and pg, including rondo who they have undeserved faith in at the moment, combined for an average of about ten points per game last year.
To be the team that everyone expects them to be, the big three will need to play their best every time they take the court.
