Especially considering that the best (Carlsen) and second best (Smith) players also left. Keita is also young, aggressive and athletic - frankly a ton of fun to watch. He's absolutely a huge loss for Utah
But BYU is also a LOT better then Utah.
Compared to Utah's players, Keita is a stud
But compared to Egor Demin (likely to be a top ten pick), Kanon Catchings (98.48), Brody Kozlowski (95.52 rating), Elijah Crawford (94.57 rating), Dallin Hall (93 transfer rating), Richie Saunders (90 transfer rating), Mawot Mag (90 transfer rating), yes it's been a surprise to me how much love Keita is getting. He's a good player and a solid addition, but so are all those guys. FWIW, I feel like Crawford isn't getting enough love
That has nothing to do with how much it hurts Utah to lose him
