Biggest brands to play for. After they get to campus and realize they’re not going to see the field for 2 years they start to rethink their decision.
In the past that meant giving up an entire year with no chance to play. If I’m at USC or Ohio St I might stick it out and wait for my opportunity. If I’m at Wisconsin or Nebraska I’m transferring for a better chance at more playing time.
Talent will spread out when it’s easier to move. The top 3-4 teams will always be those biggest brands but I’ve come to think the TP evens out the depth just a little.
