Perhaps, it's time for a reevaluation of who won the portal....
Every team portal ranking has to start with some criteria as to how to judge them. Is it just who brought in the most overall talent, regardless of needs or how they might fit? Some teams have huge losses due to graduation and or portal losses. Of course they will have more quantity of portal recruits.
Others have one or two issues to address, may find a perfect fit for what they need but not rank near the top because they don't have several high level transfers. The very best teams that are likely championship contenders don't usually have that many holes to fill. At the other end some programs bring in lots of talented transfers because they couldn't keep the players they already had that left in the portal.
The portal issue goes both ways, so maybe portal incoming minus portal outgoing is a better overall measure, and even then fit should matter. The number, positions and quality of players that did graduate also matters as does the same for the incoming freshmen class. There is no way to do a good portal class ranking in isolation that doesn't take all of those factors into account.
Teams have incoming, recruits and portal additions, and outgoing, graduations and portal losses, and all four of those are related in terms of what a team needs to do to get better, and how well they have done. Years ago the incoming was almost all based on the recruiting class, and the outgoing was mostly the graduating class.
With the ability to change schools without a one year wait, the tremendous rise in the number of transfers, and the new impact of greater NIL opportunities at other schools, the portal factor is now right up there with incoming and graduating classes in importance to many programs.
