I am not sure they are going to use the MLE, or the portion of it we can use. If we do, we end up hard capped. Depending on the player we are able to get, it may not be worth it.
As to priorities, a bench PF is now our biggest need in my mind. A bench wing is probably the second need. OKC has 18 players on the roster. Maybe we can get a useful PF with the TPE from them, or something like that. Then use vet min contracts to round out the bench. That is probably a better path than getting hard capped.
