Because Purdue has 11 transfer-eligible players, there will presumably be some portal activity soon. As of now, however, we're the only Big 10 program that remains completely unscathed. As a contrast, look at IU's 2020 and 2021 freshman classes:

2021

#30 Bates - in portal now

#71 Duncomb - in portal now

(Purdue got Furst, TKR, and Waddell.)

2020

#27 Lander - already transferred

#105 Geronimo - in portal now

#155 Leal - not in portal but in his first three years, he has averaged 10 points per season.

#157 Galloway - good player

(Purdue got Ivey, Edey, and Morton.)
