So far, that hasn't happened at MU.
The 2017 class ranking was due to the Porters who came for reasons other than CM (

Which leaves class rankings of #59 (2018), #40 (2019), and the currently unranked 2020 class of 0 recruits. So far, zero blue-chip 5-star recruits like the ones he landed at Cal & Tennessee.
I support Cuonzo, but there has been an undeniable drop-off in his recruiting. Maybe once he gets rid of the Porter Sr deadweight that will change. I'm sure the Porter injury fiasco didn't help either. Or perhaps it's just been bad luck (i.e. finishing 2nd & 3rd on all his top targets). Whatever the reasons are, hopefully they're temporary and he figures out how to land top 50 recruits again.
