They are using their potential just fine. Aces on all teams lose games all the time. And I like how we have "only" 3 solid aces, as opposed to all those other teams with more? This is on fans, not teams. When the Astros score 20 runs, it's because our hitters were so awesome. When they give up 20 runs, it's because our pitchers were terrible. No one ever credits/blames the opponents - it's never bad opposing pitching or good opposing hitting. So when everything you do is internalized by fans, then they are going to view all their failures as "beating themselves". It has nothing to do with reality, though.
