Swings
Durant - This is obvious. With him we are a contender. Enough said.
Barnes - I'm not convinced that Barnes can be a lead scorer. I like his efficiency. I like his versatility. I like that he has been on a championship team. I just don't think the Warriors are going to let him go for less than the max, and I'm not sure he is worth 20 million a year.
Wings
Batum - Batum would fit perfectly into the Celtics system and culture. He is like a better-shooting Evan Turner. He can play the point and play good defense. I don't think he ends up staying in Charlotte, but there are a lot of teams who would offer him the max this off-season (Brooklyn being one). I'd give him the max before I would give Barnes the max.
Bigs
Leonard - Meyers Leonard is a goofy player, but he has legit center size. His advanced stat adjusted rebounding percentage is top 10 among centers. He is also one of the best mid-range and three point shooters in the NBA for a big man. His inside defense has fallen off a bit this year and RPM is pretty bad this year too. But if we could get him for a 6-8 million contract, I think he could be a really good fit and give us cheap, skilled size inside. He is a RFA, so we would probably have to work some sign-and-trade.
Ezeli - He doesn't really fit our system, but his inside defense has been off the charts this year, which is something we need. Again, he is a RFA and the heir-apparent to Bogut, so I don't think he is gettable.
Motiejunas - I'm nervous when a young big guy has ongoing back problems. I'm not sure how durable he will be, but he is a big body with good skill and good inside defense. With Capella being Dwight Howard's replacement, it seems like Motiejunas could be had. He is another RFA, so a sign-and-trade may be necessary.
Guards
Tyler Johnson - Johnson reminds me so much of Dragic it's scary, but I think he is more athletic. I think he will continue to develop and turn into a starter in a few years. I would want to sign Johnson on the condition that we already made a 3 for 1 deal to thin out our roster, especially if we trade Bradley away. Again, Johnson is another RFA, but depending on how everything works out, Miami might not want to resign Johnson too.
