Let's be honest: Morris got in via the 3 W.S. rings as the tipping point. He was the #1 starter for 2 of those, and gave some unbelievable performances. But he also was the weak link in the 3rd World Series team, and only the fact that Toronto was so much better than everyone else got him that last ring.
By that logic, why not add Carpenter, whose postseason resume is every bit as good, if not better? (To be clear, I'm not advocating for this).
