Or I'm saying, the projections suck(which is my opinion), and providing my own opinion on the rotation. I'm not stating facts, and you're the one bridging the gap between projections suck, and my opinion being better. And note that I only provided an opinion on a few pitchers for the Brewers. My comments regarding the Pirates were as simple as that, these projections suck. All 10 between 4.15 and 4.8, that's terrible, it's worth nothing. I can't tell you how I think they'll do, but there's just no way all 10 land within that ERA range.
And where did I say I want projections to account for random variance? There must be something in these projections that heavily skews everyone towards average, it's the only way to explain why they think such a high percentage of pitchers are going to be near mlb average. I get that they are probably more likely to have greater variances if they make less of an effort to skew toward average, but doing it this way is pointless as it doesn't tell you anything.
