I'm with you, I think he's a good get and those stats against in the title indicate that he can play against top competition on the road at their home courts (Creighton finished at #31 AP and Iowa State #15 in the AP final polls vs when he played them) although UMKC was a pretty bad team overall.
His official name is Jamar Jordan Brown (and we've had good luck with guys who have JJ initials in their name) and he has Japanese on his X and IG profiles. Must like the culture or maybe even part Japanese from his looks???
Go Bruins!
