With Lee and improvement upon our flaws, we could compete against any team except for Golden State. That's worth it to me. I'd trade Davis to a team like BOS (they have an $8M injury exception from Hayward, that they can use in a trade for an expiring contract, and they need a backup PF, so Davis is a perfect target for them). Id ask for their 1st then flip it to NYK for Thomas and Lee(TPE). This would help NYK clear cap space for next summer. Courtney Lee is definitely good enough to play minutes on a playoff team. 40%+ 3pt shooter and would be our best wing defender. A perfect fit for our team, and is basically what we hoped Crabbe would be.
I like the Lee idea, but my proposal would be: Harkless + Meyer for Lee + O'Quinn Then flip either Davis or KOQ to Boston for their first. I'd look at trying to pick up Mario from Orlando for a 2nd rounder to replace Mo.
