The Athletic ($) came out with a fascinating story on the use of the transfer portal in the 2021-22 offseason. They tracked 2,000 different football players who entered the transfer portal, and found about 80% of the players who entered have found a new home. On average, Power 5 programs lost 16 transfers in the last calendar year.
“There were 1,054 scholarship players in this transfer cycle who left Power 5 programs. So far, 88% have found a new home and 66% will get to keep playing at the FBS level this fall, though less than one-third ended up signing with another Power 5 school,” The Athletic wrote.
