I think that's a pretty big loss - Sides simply isn't equipped to be the primary PG (and, hopefully, we didn't get her to stay and Walker to leave by promising her that).
If we don't pull a quality PG out of the portal, it'll be a reversion back to the pre-Sundell days (the first 6 years of Mittie's tenure) when he didn't/couldn't recruit a quality a PG and we frequently had trouble beating the 10-second clock.
The 2020-21 season was awful - even with Lee scoring 20+ ppg we were terrible - and a large part of that was because we didn't have a viable PG.
