That is exactly what he appears to be. Nelson would be a fun slasher who can get to the cup but there would be some fit issues starting next to Tamin. Bateman or Williams would need to be a dead eye shooter day 1 to keep the spacing on Off and defenses honest.
The driving may also be what contributes to his high TO rate. Averages more turnovers than assists.
Getting to the FT line like that is a big weapon though. Granted it'll the athleticism jump to the Big 12 would likely lower those numbers a bit as you would assume guys would be able to stay in front of him better. Would also like to see that % jump up to around 75%+. Below 70% with that kind of volume is a lot of pts left out there.
Not sure what other realistic options are left out there in the portal for a ready-made scorer though. Beggars can't be choosers at this point. The longer the portal goes the higher the prices will get as the amount of quality of players will thin out pretty quickly. Which is why TJ tried to do his work early.
The number of players in the portal is insane, but the number that are ready to play heavy minutes in the big 12 is pretty small. The number of players we can afford is even smaller.
