Just to change things up a bit from the Ray proposals, here is something that might be an interesting way to both improve the team rebounding, as well as bring in a young, scoring wing, who Danny was reportedly impressed with.
Celtics trade:
Perkins
House
Scal
Clippers trade:
Camby
Thornton
Collins
This gives the C's a nice, young, scoring wing in Thornton, and one of the best rebounders and shotblockers in the league in Camby. Even Collins has been a solid player, and might fit in well off the bench, and provide a big PG option. And perhaps the Clippers will buy out House, allowing him to return as well.
Of course the biggest downside to this trade for the immediate future, is that we lose one of the best Howard defenders in the league. However, if Perk is the best at defending Howard, then Wallace is probably the second best in the league, and even Davis has shown he can handle him as well.
I know this will not make too many people happy, but I think this is a realistic deal that puts the team in a better position for next season, while also keeping them strong (and maybe even improving them overall) this season.
