This year, the closest thing we get to that feeling is Danny Duffy. It's a different feeling, to be sure. More comfortable. Cueto was a cult of personality, and while Duffy isn't without his quirks, he's been a Royal for his entire career. That kind of relationship just functions differently than the fly by night equivalency that was John Cueto.
Coming off a start in which he struck out a franchise record sixteen batters in just eight innings (while carrying a no-hitter into the eighth as well), the coming out party is in full swing. The Czar of Gnar is on pace to put up the best season (by fWAR) by a Royals starter since James Shields was in town, and it isn't entirely out of the question that he could best him as well.
Toronto counters with Aaron Sanchez (11-1, 2.71 ERA), who's you know, pretty good. Pretty good. The Blue Jays themselves are pretty good.
