Wow. Nothing like offering a top 50 player 3 1/2 months before NLI signing day.
The KUs of the world can swoop in at the end of the recruiting cycle and walk away with some upper level recruits, but typically the Nebraskas of the world cannot. We generally have to build a relationship over a long period and then hold on when the big boys figure out we've got a player. There must be more to this particular story that we've extended this offer and didn't offer, for instance, the #4 player in the nation who's also a SF and uncommitted.
He's slender like Roby, but that's about where the comparisons stop. From the very brief video I saw of him (very small sample size) my impression is that this is a very skilled player who's probably a better shooter than Roby but doesn't have Roby's explosive leaping ability. If he had Roby's ups, he'd be top 20 instead of top 35.
The thing that's putting Roby into the first round draft pick discussion is that his skills are catching up to his elite athleticism. This kid appears to have those two parts of the equation reversed. He's more skilled than he is athletic. Which isn't to say he doesn't have athleticism or can't build on what he does have; it's just that his skills are at a higher level.
Hopefully, this is more than just throwing an offer out there and hoping. Hopefully, there's some reason to believe he might actually have some interest.
