johnson would have 2 years if he gets a medical redshirt in 2024.Johnston will likely be back, he only played in 3 or 4 games his frosh year prior to injury so he will likely get a Med RS. They do lose Sloat, McGuire and I think a few other starting defenders. Most of the O is back though save for Sloat and the UVA transfer Mencke.
UVA brings back a lot offensively and could be very dangerous again but they do lose Sunderland, Marek (starting goalie), and multiple starting defenders including Murnane and Shroter and I believe at least 1 SSDM. They also some ancillary pieces in Balsamo, Inderlied etc. Terenzi is also technically a SR but I think also likely a candidate for a med RS for injury. He may actually have 2 years left
UNC returns almost everyone on offense and should be the unanimous pre-season #1. They have some losses on defense including both starting SSDM's and 1 long pole but that's about it. If your looking for a silver lining their current JR class is like this years SR class for SU, a lot of talent will be leaving next year including Duffy, Petro, Wambach, starting LSM and others.
ND is a mixed bag. Return a lot but lose Yago and a # of others.
schroter has another year, terenzi conceivably has 2 if he wants them.
