According to some sources, players who entered the portal prior to January 2 can still transfer if they have not signed a financial agreement with another school (aka are not taking a scholarship and/or are not taking classes in the spring semester). Unsure if we'll see anybody take advantage of that.
The second transfer window is Apr 15-30. I expect our lineups are set going into spring practice, but maybe somebody elsewhere loses a starting job in spring practice and wants out. That period will be crucial to filling out depth especially on DL.P
