That’s a tough one. I’ll rule out Manu due to the fact he will only have played at BU for 2 seasons and the 2nd has just started. But, he’s certainly picked up where he left off last season so far. FWIW, last season he hit 40% of his 3’s.
That leaves us with two. LAC3 in 4 years sits 2nd All-Time Big12 with 388 3’s (one 3 from 1st), hitting 39% of his attempts over that span. H3SLIP is 7th All-Time Big12 with 301 3’s, hitting over 43% of his attempts. It’s close, but I’m gonna have to go with LAC3.
