The warm fuzzy:
Injuries aside, our starting 5 looks to be the best in the league next season.
Now the cold water:
The problem is that as the Big Three age, injuries will become more likely. Yes, KG should be fine, but it may take him longer to recover from surgery than anticipated, and he may be slower when he comes back. Ray ray and PP have been relatively injury free this season, who's to say the same will happen again next year? These guys are getting older, and are more prone to injury, plain and simple.
Some more cold water:
The Cs already have $72M tied up in salary next year. If the Cs can tie up Powe and BBD for "not much money" and use the full MLE for a player like Rasheed (as some suggest), that would put the Cs salary at about $80M. Will the owners pony up? Maybe.... maybe not.
The bright spots:
If the Cs can retain BBD for a reasonable amount of money, then they have at least the core of a bench (House, BBD). Expiring contracts should be in demand, so Tony+Scals* should be able to be used to bring back a decent bench player (though not Posey, as someone said above, nor Nocioni -- been there and could of done that, and the Cs passed because of the high cost in both cases). Also, because of the desire of many teams to make a run at Dwade/CBosh/LBJ, there should be some decent bench players available cheap. I am thinking, for example, of a player like Matt Barnes. Few teams will throw an expensive long term contract his way.
* The Draft
One area we could see some action would be the Cs trading Tony+Scals for a draft pick +player with a longer term contract. In general, though, I wouldn't be surprised to see the Cs not make any draft picks this year. Cs already have 3 young players to develop (Pruitt, Giddens, Walker) and it was hard enough for those 3 to find playing time.
