I don't know if JJ will make his free throws, and I don't know if LL will improve his hands enough to be an offensive factor against a swarming defense.
However, I don't think either of those things will keep KU from winning games because there is so much talent here.
JJ is such a good passer and scorer that the only way to slow him down would be to pull a hack a Josh type of gameplan. Unfortunately, most teams just don't have the wing talent to do that with their better players, and they can't afford the drop off offensively if they put in end of the bench guys to do the fouling. That means that Josh's FTs will come within the flow of the game. He will probably shoot about 60%, which should be enough since at the end of games, the ball will be in Frank's hands or Devonte's hands and they will make their free throws.
For Landen, he needs to chip in offensively where he can, but the big things for him are defense and rebounding. He does both of those things well, and he made probably the biggest defensive play of the night last night with his hustle to disrupt Wainwright's shooting motion on what could have been a game tying three.
We don't need Landen trying to score in double figures. With our current rotation, Landen will never be more than the fourth option offensively on the floor. I don't say that to mean he shouldn't get touches, just that the gameplan should never revolve around him scoring. He's done well at the rim, and the advantage of playing four out is that Landen is almost always in the paint where he has to be accounted for because of his rebounding ability.
I guess my point is that KU is in good shape right now, so long as the current rotation stays healthy. There aren't many reinforcements available, so health is absolutely critical.
Also, the big take away from the last two games is that in big games, Josh absolutely can and will step up to be our best player. 20 and 10 on the road at Kentucky, followed up with a 23 and 10 against a top 5 opponent at home. That's what you envision when you recruit a player like that.
