Playing the Waiting Game
What about Gattis, Elmer Reyes (or) Tyler Pastornicky, and Juan Jamie (or) James Russell to Baltimore for Hunter Harvey and Jimmy Paredes
I'd love to see how accurate the steamer projections were last year. These predictive tools are close to useless ofr young players who haven't logged significant major league innings.
I'm with you on this [MENTION=7]thethe[/MENTION] so I found some interesting numbers:

It's pretty obvious that these "projections" are almost always higher than the actual numbers.
This is wrong. The weights aren't just arbitrarily chosen. They are obtained in a sophisticated way, likely through regression analysis which is very precise and based off thousands of data samples.
The biggest issue with projection systems is they are excellent at predicting the majority of players since the majority tend to play to their averages, but struggle predicting which players will drastically outperform or underperform their averages.
The issue that projection systems have with Julio Teheran is that his underlying stats suggest that he's been overperforming (FIP) so Steamer is predicting that he's going to regress back to what his peripherals suggest.
Steamer isn't being unfair to Julio. It's a model so it's lacks the ability to be bias. If Julio continues to outperform his peripherals then the system will start to incorporate that more and more.

If you chose Michael Brantley, Victor Martinez, Jose Abreu, and Nelso Cruz, you could conclude "well it looks like the projection systems haven't caught up to the inflation of offense". Which, of course, is a wrong conclusion but the exact same method the poster used earlier. Even though he was trying to pick random, it's a biased method of choosing players.
Projection systems are using what is called the mean projection or a 50th percentile projection. It's the likeliest outcome of any, but not by much. It's not saying its unlikely for a player to outperform or underperform either.
And as for offensive or defensive inflated statistics, steamer forecasts league adjusted statistics, so they do account for inflation inherently.
Please tell me how this was anything but random.
I find it highly unlikely you randomly chose Kershaw, Felix, and Kluber out of the hundreds of major league pitchers.
How did you choose them?
I chose the best pitcher(s) from almost every team. My point is that as good as most of these pitchers are, and some have been for a while, "projections" still tend to be higher than they should.
Well try the same exercise with the fifth best starting pitcher on every team and I guarantee you that you'll come away with the opposite conclusion.
A poster posted an excellent article a couple pages earlier that addresses the accuracy of projection systems. In it it discusses why projection systems have a difficult time predicting break outs and break downs. You cited examples of Steamer failing to predict break out performances. If that was point you were making then I find it to be a rather good one. But you claimed "projection" (the quotation marks an obvious slight) systems underestimate most pitchers which isn't correct. Choosing the best pitchers in the league doesn't prove your point.
So take R.A Dickey for example (who was suppose to be the Jays best pitcher) and I guarantee that his final numbers were a whole lot worse than the projections. I'm not trying to argue with you because these projections are the best we as fans have at predicting a players production but to say a Player is going to be worse than what he's continued to do at the highest level is absurd. I will later on tonight do a chart with some 5th starters just to see.
You could do that... Or you could just read that article. The latter would be far less time consuming. You would prove zero point to me by doing "some 5th starters".
If you want to prove a point then compile a list of every single pitcher in baseball and then compare the projection and actual performance. If you notice a trend of pitchers outperforming their projections then I'll take your side on it.
Rumor is Gattis is heading to Houston now.
