Looking at their lineup, I'm guessing the rotation will now be:
PG-Hailey Van Lith, Grad Student
SG-Mikaylah Williams, Fr
SF-Flaujae Johnson, So
PF-Aneesah Morrow, Jr
C-Angel Reese, Jr
Bench:
Sa'Myah Smith, So
Kateri Poole, So
Last-Tear Poa, Jr
Aaliyah Del-Rosario, Fr
Angelica Velez, Fr
I wouldn't be surprised if Williams comes off the bench in favor of Poole, though most #1 or #2 recruits start from the get go.
Front court rotation is elite with Smith backing up Reese/Morrow. Backcourt also looks solid. This is the #1 team in the country on paper going into next season.
The big question is how all of these players will work together, and who will be content taking on a smaller role (being a screener, rebounder, taking fewer shots, etc). I think every player will go into the year planning to sacrifice for the greater good of the team, but intention is often easier than implementing adjustments. Last year Reese took 15.6 shots per game, Van Lith 16.8, Morrow 24.7. They're all used to being the star, and now a couple of them will relinquish that role. Players putting ego aside and playing unselfish basketball will make or break LSU. Someone (likely Morrow) will need to take pride in being a screener and doing a lot of the little things that aren't as fun or flashy for the betterment of the team. Van Lith will need to take pride in being a passer and getting teammates involved.
Worth noting, this entire roster could return for 2024-25 as well. Even if Reese/Hailey Van Lith go pro, the crop of returning players are elite and should have LSU a top 3 team the following season as well. There will be some massive battles in the SEC between LSU and South Carolina this year and in years to come.
