Tennessee prides itself on defense, but coach Rick Barnes is calling on the Volunteers to bring the “confrontation” mentality to the regular-season finale on Saturday afternoon.After a 78-76 defeat at Ole Miss, the No. 4 Volunteers (24-6, 11-6 Southeastern Conference) need to beat last-place South Carolina in Knoxville, Tenn.”It’s ridiculous,” Barnes said after the Rebels’ Jaemyn Brakefield scored all 19 of his points in the upset’s final 10:24 and was undeniable in the paint.”We talk about having confrontation. We play like we were — that’s soft, honestly. That’s being soft. That’s you not really trying to go in and make plays on the ball.”In the final 20 minutes, Tennessee built an eight-point lead but squandered it with nearly 16 minutes left before Brakefield happened.”They made shots on us,” said Barnes, whose team lost the points in the paint battle 46-20 and the offensive rebound tussle 15-8.”But again, you let a team get comfortable and you’re not as aggressive and you’re not playing smart. Offensive rebounding can just take the wind out of your sail.”Though its hopes of a No. 1 national seed were critically damaged, Tennessee can guarantee itself a double bye in the SEC tournament in Nashville by defeating the floundering Gamecocks (12-18, 2-15).Vols leading scorer Jordan Gainey netted 19 points on Wednesday to eclipse 1,500 career points. Team leader Chaz Lanier (17.7 points) swished 3 of 8 from distance to put him at 102 made 3s, joining the North Florida transfer with Chris Lofton and Santiago Vescovi as the only Volunteers to breach the century mark in a season.Dating back to 2017-18, the Rocky Top program has won 11 of 13 against South Carolina and is 31-10 all-time at home.Regardless of its outcome in the Appalachian Mountains, South Carolina knows its situation in the Music City next week.
