LSU had a recent run of games in which it overcame halftime deficits to win.The Tigers seem to have gotten past that, but now second-half fall-offs are becoming a concern.LSU will look for a complete 40-minute performance when it faces Stetson on Tuesday night in Baton Rouge, La.The Tigers (8-2) are coming off a poor second-half performance in a 74-64 loss to SMU on Saturday in Frisco, Texas.”The two things that really stand out to me in the second half are 13 turnovers and 26 points allowed in the paint,” coach Matt McMahon said on the Tigers’ post-game radio show after his team got outscored 47-31 after halftime.LSU committed four turnovers in the first half but had 11 in the first 12 minutes of the second, which contributed to the points in the paint. McMahon knows that has to get fixed quickly with the start of Southeastern Conference play looming.”That’s just not going to be the formula for us to have any sort of success moving forward,” McMahon said.The Tigers had won four straight games prior to Saturday, and in the first three of those contests, they played strong second halves. However, they got outscored 44-38 in the second half of an 80-71 victory against Florida Gulf Coast on Dec. 8, setting the tone for what happened Saturday.
