He is overrating the White Sox foundation for future success.
If it comes to the team's pitching, then yes, the Sox have a good foundation. Teams also have to score runs to win games and there is not much in the pipeline when it comes to hitting in the minors or even at the big-league level.
Supposed franchise conerstones such as Luis Robert Jr. and Andrew Vaughn are proving to be nothing more than role players. Robert Jr's career is in a tailspin as he continues to not hit this season. Vaughn is nothing more than a replacement-level player.
Korey Lee has cooled off so quickly that he is definitely nothing more than a career backup catcher. Dominic Fletcher lost precious big-league at-bats so Tommy Pham could be showcased to the rest of the league even though his trade value was firmly established.
At the minors, top-hitting prospect Colson Montgomery is struggling to hit consistently at Triple-A. He was projected to be a superstar. Instead, he is looking more and more every day like his ceiling is an everyday regular shortstop whose career season will be like a 1.5 fWAR.
Bryan Ramos and Edgar Quero can be superstars and George Wolkow might be a stud. However Wolkow is 18, Quero is battling a back problem, not good for a catcher, and the team is having Ramos taking fly balls because this front office is convinced Miguel Vargas can play third base.
This team not only needs a superstar player in the lineup but a couple of very good, above 1.5 fWAR players and there is just not much depth in the minors to produce that.
