I didn’t realize a player could have four years of eligibility in each sport.
You have 5 years total to use up 4 years of eligibility. If you can manage to squeeze more than 1 sport into that 5 year window, more power to you.
The twin sister of Stanford's Brittany McPhee, Jordan, played basketball at D2 Seattle Pacific. She competed in track at least 1 year at SPU. After playing 4 years of hoops she grad transferred to Gonzaga and participated in 1 year of cross country.
Delle Donne played 1 year of volleyball at Delaware and then starting the next year competed in basketball for 4 years.
I'm not sure how this worked out exactly, maybe there was a redshirt in there somewhere. In a really unusual career path, Demetri Goodson played basketball for 3 years at Gonzaga. Then he transferred to Baylor to play football, was also there 3 years. 2 of the seasons there he only played in 4 games, so maybe he got some kind of waiver. Then on to the NFL.
