I like the way this team has played lately and a lot of things are becoming clear. It is clear Cousins can be the guy, he is having a MONSTER February and a good season overall. Tyreke likely won't be anything more than a second option and is not a PG, but has played the 3 well enough to pass there (though undersized, his quickness makes up for it). Salmons is starting to realize his role now at this point of his career, a solid role player and defender, same with Garcia. Hickson won't be back next year, in favor of Thompson, with the recent comments and both their play on the court. Thornton is a legit 20 PPG scorer. Now, Thomas and Jimmer still have questions surrounding them, but at the very least, both serve as capable backups.
The thing missing on this is a true, play-making, experienced PG. First guy that pops into my head is Rondo and I think the Kings are a great fit. We have money, young talent and draft picks, all what the Celtics want. Offer up this years first rounder (and next year if necessary), JJ Hickson, and either Thomas/Jimmer.
This team doesn't need more draft picks, we need players to fit the system now. Rondo/Thornton/Tyreke/Hayes/Cousins- Thomas, Thompson, Salmons, Garcia off the bench. That's actually a pretty damn good defensive team.
