That's a pretty limited piece of info, but it at least supports the argument that if you are not a blue blood, you probably are better off relying heavily on portal players.
Of course another argument would be it's still early enough in the free transfer era that we're not at equilibrium yet and the optimal strategy for each school is going to continue to change as other schools change their approach.
Or another explanation would be blue bloods don't lose players they want, non-blue bloods do, so of course the non-blue bloods have a lot more transfers, and the ones with good coaching and talent evaluation and a little bit of luck will rise to the top with the blue bloods, but they'd do even better if they could maintain more consistency.
I think all of those are true to an extent. You might see the story change next year, and some of the non-blue bloods that did a good job of retaining young talent and developed it might rise to the top with a veteran heavy team. I do think you'll start to see that as time progresses and players get less enamored with transferring every year and collectives get more focused on retention. I think we're at least another year if not two from that dynamic happening. We're certainly not in a position to benefit from that because we haven't retained the young talent to my knowledge.
