So you're saying this team makes no sense... but you're continuing to have patience while the free agent market dries up?
The only thing that "doesn't make sense" it's that we've yet to acquire a center. Doesn't mean that the other pieces, the "core" pieces, don't make sense.
I love the idea behind the 3-guard rotation of Rondo-Bradley-Smart. I like Jeff Green at the 3 (we need a better back up), I like Olynyk and Sully as PF both of them capable of sliding to the center as needed in a 3 man rotation.
The ONLY real issue we have right now is the lack of a true center with a semblance of talent. Guess what... all teams have wholes in their roster.
X Factor? Wallace, I'm not sure what he has left... I don't mind him as a back-up SF/PF type. But if we could get rid of him he would be gone. Not a big issue.
Bass, I'm sure Ainge is trying to trade him. He's an expiring deal, not an issue.
So, what's your REAL issue with the roster? As far as I'm concerned we have a pretty [dang] good roster 1-4 with a nice mixture of talent, youth, and experience. We need to solidify the 5th spot. We still have the trade exception (not sure if we're going to use it). We still have the full mid level... etc., etc.
All that said, you can't compromise next year's free-agency much more by spending more than a one-year contract if the player you're acquiring isn't a big impact type. You're better off just waiting it out.
