You miss the point entirely. I would rather rotate sophomores and juniors into the vacated rolls of juniors and seniors than freshmen for freshmen and sophomores. Ask Billy Donovan. Are you assuming that Xavier, Butler and Gonzaga have no RS Freshmen, Sophs and Juniors. If so, you are wrong.
no I'm assuming that since they were senior dominated teams those sophs and juniors probably aren't going to step right in and replace the seniors?
Xavier might be able to they were a very balanced scoring team they had 4 guys who scored in double figures and 2 more who were just under 10 PPG. 3 of those were seniors of course including 2 of their top 3 scorers. it's harder for schools like that to replace that many starters in one year because they typically don't "reload" in recruiting as easily as a power school does.
Butler graduated 60% of it's scoring this year. Yes they have underclassmen but they were a senior dominated team much like Washington State was who pretty much everyone assumes will have a large dropoff this year.
Xavier was deeper but Butler wasn't very deep at all, they basically played 7 guys and 3 of them are gone now.
The reason Florida had problems is they literally lost 5 starters 3 of whom were lottery picks. They went from the most talented starting 5 in the country to a starting 5 almost entirely of freshmen. You'll note nobody was picking Florida top 5 in the preseason this year either, same reason.
The schools picked at the top here are all losing key guys but probably not enough to decimate the team. UCLA could, Kansas could(Rush, Chalmers, Arthur and Collins are all considering leaving reportedly) but the author makes it clear he's assuming some key guys return on those teams.
he's not just blindly penciling in teams because they're name teams he's guessing who will leave who won't and then ranking based on that.
It's too early to do that because of the draft but the man has a job to do so he does it by guessing.
