This really isn't a fair analysis. In the 2015 class, what was Edsall to do with Blackwell, Nazir Williams, and John Robinson IV who were disciplinary issues as they were arrested? I think 8/23 (not 4) of the 2015 class were Diaco issues, not Edsall issues: Ryslik, Parker, Blackwell, Battle, Lee, Richardson, Williams, Robinson.
Also, in 2016 class, isn't Skanes still here? I count 12/16 in the 2016 class were at UConn for 4 years which means they all had a fair shot to prove themselves and get playing time.
