IIRC, 2J recruited Koroma telling him he was needed and could contribute right away. I think coaches were smart on this one and just knew a beast is a beast.
I've seen it all on here. Stupid posts saying Koroma was just a desperation grab by coaches and nothing much was expected. That's bull. I believe coaches knew EXACTLY what they were getting. Had to have some faith he could bulk up, but they knew they were getting a star from the highest level in HS.
