I haven't read in any of the articles Brandon has posted "I'm going to grade Twins' pitchers compared to every single pitcher in the MLB."
That has nothing to do with my point.
The author clearly doesn't think the grades are arbitrary and/or meaningless. If he did, he would have simply done the write ups without including the grades.
I happen to agree that the grades don't need to be on a league wide curve, but again, that's besides the point.
People disagreeing with his grades don't necessarily mean they think he did a bad job. I just don't understand the need to call people out for having a different opinion.
