We shouldn't get wrapped around the axle on the difference between "talent" and "impact player".
Ayo, Kofi and TSJ were all All-Americans, players who completely dominated college basketball.
Between the incoming player classes of 2004 to 2017, the entirety of two coaching administrations, we didn't bring in a single player with anything close to that kind of impact. (I think the only All-B1G First Team selection in that span was Demetri McCamey, correct me if I'm wrong, Hill, Paul and Leonard were not)
KJ and Riley have future upside as true stars in the NBA, they could end up among the most famous basketball players on earth, but it's very rare for freshman to have that kind of impact in college, especially during this era.
