Which areas should Barnes prioritize in the portal going forward?

Now almost one month into the offseason, coach Rick Barnes has made ample progress in the reload of his roster, snagging several players in the transfer portal.  

Four of the five recently committed Vols are guards, while 6-foot-10 Miles Rubin serves as the only big man addition thus far.  

As of now, only two Vols from the 2025-26 season will return to Barnes' squad next year, tasking the coach to almost entirely reconstruct his roster.
