But if one believes Revis will shut down Calvin, then why give him half a touchdown at all? It skews the numbers. Also skews the numbers for Burleson. Maybe not when comparing him to Calvin per se, but when comparing him against Ward, Walter, Driver, or Evans that particular week.
Ramblin, you're kind of setting up situations to argue against that aren't what they are doing... or if they are doing then they would definitely be wrong.
If they think Calvin gets
totally shut down by Revis, then he should have 0 TDs, yes. And if they have him at 0.5 TDs that means they don't think he's totally shut down. It would mean they think he would normally score TDs more often but that the Revis factor is going to drop him down to 0.5 TDs that week when against another opponent it might be higher.
So saying "he has 0.5 TDs" and saying "they believe Revis will shut him down
completely" (and I'm adding the completely for clarity) is something FBGs wouldn't put out there. Or if they are, then I'd be on your side. But I haven't seen it. You're creating a situation then saying they would give a projection that they wouldn't give if that was truly their feelings on it.
In week 14 last year, 37 different WR were projected to catch 0.4 to 0.6 touchdowns. In week 13, it was 38 different WR. In week 12, it was 36 different WR. That's absolutely hedging your bets and not really telling your readers anything. A cynic could claim every player is wrong every single week because no one ever scores half a TD. FBG will claim they are the most accurate but the majority of players every week will score 0 or 1 TD and they project right in the middle for so many of them. In a standard scoring system, WR14 and WR29 are separated by 1.2 points, which is basically nothing.
This is the difference between projecting individual specific players versus projecting a nameless set of results. If I were to come up with a projection for how many passing yards
the top QB in week 1 will have, I'd probably say something in the neighborhood of 350.
However if Peyton Manning is my top QB, and I were to project Peyton Manning's results, I should not project him at 350. The odds are very good that he won't be the top QB this week even though I think he's got the best chance overall. If I think he has a good matchup I should probably project him in the 300-320 range... which would be 40-60 yards better than his career average. If I think he has an average matchup I'd put him down around his 260 yard career average.
I think your objection is due to a common misbelief that projections should look the same as final results. But the reality is that they shouldn't. If my goal is to project what Peyton is actually most likely to do, I need to focus on him and not on what the QB who will lead the week in passing will do just because I think he has the best shot to be the top QB that week. I don't have a 100% certainty he's going to be that top guy so if I want to give the best projection I can, it needs to be lower than I would project the top QB at.
Various dice examples have been given several times already I believe. If I have a number of different sided dice... a 4 sided, a 6 sided, an 8 sided, a 10 sided, a 12 side, etc, on up to 20... it's probably very good odds that a 15 or higher will be rolled. If I'm projecting what the highest result will be, I should probably say around 15. But if I'm trying to project what the 20 sided die will roll, the most accurate prediction for it would be to say 10.5.
Now is that useful to you? You bet it is. If you're deciding between the 20 sided dice and the 18 sided dice, you know that your expectation for them is that the 20sided will average 10.5 and the 18 sided will average 9.5. That tells you just how close they actually are to each other... even if the 20 might toss up a 19 while the other dice could pop up a 2.
While football does have a little more that lends itself to predicting than dice rolls do, it is still very much something that is difficult to predict. It's much easier to predict a season's worth of games than it is a single game... and predicting a season accurately is very difficult.
What you see as a problem is actually an indication that FBGs understands the truth about how hard it is to predict these things. Rather than give you what they know is the wrong answer, they are giving you the best one that doesn't try to pretend it knows more than it does.
When they don't have a huge spread across those players when predicting a single game for them, what you should be walking away from them with is the understanding that they are telling you there often isn't that huge of a difference in what you should expect from one player to the next in a given week.
