SMU needs every victory it can get to bolster its NCAA Tournament chances and can’t afford a loss when it takes on Florida State on Saturday afternoon in Tallahassee, Fla., in the regular-season finale for both teams.The Mustangs (22-8, 13-6 Atlantic Coast Conference) have alternated losses with wins over their past six games, damaging their fading tournament hopes. But with a victory on Saturday, SMU can secure a double-bye in next week’s ACC tournament and only need to win three games in said tournament to potentially clinch the conference’s automatic bid.SMU is ranked 46th in the NCAA’s NET rankings and neither ESPN nor CBS Sports is projecting the Mustangs to make the tournament field.Coming off a loss at Stanford on March 1, the Mustangs barely avoided back-to-back losses on Tuesday with a 77-75 win over Syracuse on Keon Ambrose-Hylton’s tip-in with 2.9 seconds left.”I think (the win) gives us confidence to go in and play great on Saturday,” SMU coach Andy Enfield said. “Whether we win or not, who knows, we just have to compete, but I feel great.”For Florida State (16-14, 7-12), the only way to make the NCAA Tournament is by winning the conference tournament title and an automatic bid. Saturday’s game will mark the final home game for longtime Seminoles coach Leonard Hamilton, who is retiring at the end of the season.Jamir Watkins, who is averaging 18.5 points per game, continued to impress with a team-high 18 points, eight rebounds and five assists against Virginia on Tuesday.
