The portal is not absolute. Recruiting high school players lends to a huge pool of players with plenty of potential and a bunch that you can develop. The portal leaves every team in the country vying for a few bona-fide stars, a few worthwhile projects, and a ton of rejects. I wouldn't hedge my bets on the portal for success every year.
in 2022 signing classes, noticed that many schools signed much less than the 25 they could have. Could be roster management due to COVID and players getting an extra year.
I prefer UT get and retain high school players. Think that is better for long term success rather than depending on portal. JMO. But reality is your going to have to depend on youth frequently so your high school signees had best be very good.
