I mean, look. The guy was probably the best pitcher in baseball for four years, and that absolutely counts for something. He struck out everyone, threw lightning bolts, was unhittable, and was basically must-watch baseball. Maybe he didn't have a lot of wins because he pitched for bad teams, but that's almost irrelevant to the Hall discussion.
If you'd asked this question at the end of that fourth gonzo season, then yeah, he's basically a lock once he gets to ten years. But it didn't last. Injuries and life get in the way.
The question here is whether I'm talking about Luis Tiant, Dwight Gooden, Johan Santana, Dave Stieb, Mark Langston, Bret Saberhagen, or deGrom. Because you can say that about those guys, too. And they're not HOFers either.
