Sure! McMullen snuck one of the Pitcher of the Year awards that Toner missed during his streak of dominance due to injury in 2016, and missed the triple crown by the strikeout crown that season - he came second behind teammate and HOF Rod Taylor by 15 K; Toner was fourth despite missing about ten games.
That aside, McMullen's claim to fame was longevity; he didn't miss a beat or a call to the mound for the first 14 seasons of his career. He had a handful of brief day-to-day issues, but was unable to play only twice during his career, and then for a total of seven days.
Of course the numbers aren't as flashy for him despite him having more wins and more strikeouts, but his ERA is half a run higher and the WHIP is nowhere near Jonny either. I don't think he's a first-ballot case, but I did vote for him anyway because I'm not some "nobody goes in first ballot!" jerk.
