According to their 247 board:
1) he wasn’t very good last year (he was a true freshman), but he had potential to make a big jump this year if he stayed healthy.
2) this isn’t an injury situation. Seems like he is overwhelmed due to parental pressure surrounding NIL and a coaching change? My completely uninformed guess is that one or both of his parents pressured him to follow Fisch to UW. Either because they liked him and/or because UW would offer more NIL. Or because playing in the B1G could potentially lead to a better chance at a higher draft grade.
