I think he'll transfer because playing here, point guard or otherwise, is detrimental to him showcasing himself. I don't think his frustrations are born out of the benching and suspensions but out of this amazingly restrictive offense and that he's been told that he needs to do even more to fit the system.
You can be of the opinion that he's overrated all you like but if he decided to transfer he would likely be the most sought after transfer this season, even more than Sulimon because of the amount of eligibility left.
