A couple snippets:
WKU is a model. It added Bailey Zappe, Jerreth Sterns and other players from FCS Houston Christian in 2021, and Zappe set the single-season FBS passing record. Reed continued WKU’s transfer success in 2022 before the portal opened again. The Hilltoppers did lose five players to Power 5 schools in this cycle, but keeping Reed and others shows there is a path forward. It’s not always just a bidding war.
“You can win some of those battles,” head coach Tyson Helton said, “by being open and honest and coming out to players with a pure heart.”
There's a lot more that could be mentioned.
But basically it comes down to this: People are going to do what's in their best interest & sometimes it's in a person's best interest to go into the portal and see what's out there and decide what to do.
