Gunnar Henderson is viewed as a potential rookie of the year candidate, a potential cornerstone for the franchise, and an overall key piece for us moving forward. He fared overall pretty well in his call-up last summer and has nothing left to prove against minor league pitching. Yes, he gets gifted a roster spot.
Cole Irvin didn't debut until he was 25 and is on his third team in 5 years and has a career 4.59 ERA. The Oakland Athletics, arguably the worst team in the majors, didn't view him as a core member of their organization when they traded him for a minor leaguer. When he was acquired, it was widely reported that he would have a rotation spot, he wasn't acquired for any other reason.
Those are the differences in the two players as I see them and if you can't understand why I called your claim on Gunnar Henderson's roster spot false equivalency in comparison to Cole Irvin's roster spot then I'm not sure what to tell you. They couldn't be any more different, therefore I have no issue with Gunnar Henderson being gifted a roster spot and I had a bone to pick with Cole Irvin being gifted a roster spot.
