So let's go:
Since we're dealing with rate stats here (I threw in homers just for fun) I don't have a huge problem with averaging these numbers.
And now, the mega-projection: .286/.322/.435, down from .325/.354/.480 last season. The average actually looks like a good representation of the numbers: you've got the extremely negative PECOTA and extremely positive Marcel projections counter-balancing each other, then four others that are all around the average. I guess technically the average is always reflective, but in this case, you can see it very easily.
