I think it is pretty well established that the Wolves need a larger wing (a 3 and D type) and a 3rd big.
Do you make a splash in FA going after someone like Ibaka or Otto Porter on a max (or close) contract? This would operate on the assumption that there would be limited cap space several years down the road but that is an issue several years away and I believe the Wolves can continue to resign their own players (like KAT and Wiggins) and just move into luxury tax territory. Lavine and/or Dieng would likely have to go at some point though.
The draft has a couple of players that fit the Wolves but there are so many small guards at the top limiting the choices for the Wolves. It is possible that they land a 3/4 that can develop into a role player by his 2nd season with upside for more though.
