Honestly, what players on this team can you actually imagine starting for this team if it becomes a contender? Are any of them irreplaceable?
I like guys like Bradley and Crowder, but I'm not sure either are long-term starters (Crowder is playing really really nice, though). Thomas is probably best used as a backup. Amir is here to be traded. Sully is probably not here long term. Smart has been horrible. Olynyk can shoot, but is limited in a lot of ways. Turner is probably a backup.
I know we have tons of picks, but I wouldn't mind the team cleaning out more space, getting more picks, getting another lotto pick this season and trying to hit a home run through the draft and free agency. If we can't buy, we should sell. We're going to end up needing to let players walk for nothing eventually. We're overloaded with mediocrity.
