Transfers have happened for decades. The Ole Ball Coach complained about QBs transferring back in the 80s or early 90s. It's easier now, so they do it more, but I don't think the kids have changed. Aristotle complained about the younger generation hundreds of years BC:
“[Young people] are high-minded because they have not yet been humbled by life, nor have they experienced the force of circumstances.
…
They think they know everything, and are always quite sure about it.”
The new generation isn't any worse, they just have more chances to do what's always been done.
