Not really. Arthur Kaluma hasn't committed yet; he's much more of a 4, though. Julius Marble has a year of eligibility, but he has a pending sexual assault case. Not sure anyone is taking a flyer on him.
If any program is in need of a quality big man this late in the game, best options are either getting hs juniors to reclassify, or going the international route. Obviously you'd have to sway these European bigs to turn down pro offers, which won't be easy. I've heard Noa Essengue has had some interest. And this 7 footer from Turkey looks nice. There are plenty of others that could be persuaded.
