If all 4 leave, playing "Classes" would leave Montez Mathis and RHJ as seniors, Mulcahy and McConnell(he was going to redshirt) as Juniors, Palmquist, Reiber, Mag, and Cliff as Sophomores, Jaden Jones and Jalen Miller as Freshman. That's 10 scholarships, I guess prefect scenario would be a Grad Transfer, Junior and another Freshman(3-3-4-3), if not leave one open.
Spitballing the lineup with starters would probably be Mulcahy, Mathis, McConnell, RHJ and Cliff, backup by position Jalen 1, Jaden 2, Palmquist 3, Mag 4, and Reiber 5 with what is staying.
Wouldn't shock me Doucoure to Fairfield.
Myles and Geo will all depend on what they do in March Madness. If they make a legit run S16,E8, they are probably gone. If Geo stays, you might lose Mathis if what happened on Wed meant anything. I think JY is gone either way, his stock is never better right now and I bet he will impress in a NBA pre-draft combine.
