What do we do with Trey Smith?

As we look to the off-season, we know that the decision on Trey Smith will be the biggest thing on the horizon. Do we pay him $20+ Mil AAV for 4-5 years and be unable to do anything notable in this off-season (and likely future off-seasons with McDuffie and Karlaftis deals upcoming) or do we tag and trade him (likely for a 2nd), hoping that Kingsley or Wanya could fair better at guard than they did tackle.
