Error Bars
With football season officially over, which makes the space from now until Spring Training starts a blank void of regular season NBA walk-throughs and NHL non-events. For baseball fans, the Hot Stove is stowed away for the summer so we're left with...Projection Season.
PECOTA dropped last week and your Toronto Blue Jays ZiPS projections should show up on Fangraphs this week. Steamer's been here all along, putting the Jays in the 84 win range. Numerical projections are easy to hate and hard to love, mostly because of the indelicate way in which they're handled. Either taken as gospel or thrown aside without a second thought, the output of these complex systems does offer information worth considering - with context and an eye on the bigger picture.
The vagaries of the projections aren't important. That one algorithm likes the team, as currently constructed, more than another isn't the important information imparted upon us. If adding the WARs was all it took to win baseball games, nobody would bother to watch.
There are, however, important lessons to learn from the ledger lines and aging curves set before us. Not as prediction of what might happen over 162 games but as an indication of talent on hand and how that talent spreads out.

Projectin' Thangs - Pitchers

Before I dump the "relevant" data, I need to convey one important message: I love Ricky Romero. The more I read and learn about him, the more stock I put in stories of his otherworldly make up. From his radio hit the day Jose Bautista signed to his cinematic Nike commercial, I find so much to like about Ricky Romero. Dude rules. Also, a great pitcher!
That silky smooth segue brings me back to the long-forgotten projection summary posts I started weeks ago. With the hitter comps out of the way, the focus switches to pitchers. Projecting pitchers is hard because pitching is crazy. Guys regress, they improve, they lose the ability to locate certain pitches or it all comes together.
A recent Fangraphs community study shows mechanical projections aren't as good pitchers as they are hitters, but we won't let that stop us from having fun, now will it? There are only five pitchers selected below, not because of my inherent biases but because of available information. It isn't ME that hates Jessie Litsch, it's the computers.

If, by chance, these five men make the lion's share of starts for the Jays in 2011 and the worst of the lot finishes with a FIP just north of 4.00, I will throw a party. Nothing too extravagant but some nice sandwiches, some decent bottles of wine, a tasteful quartet, decent venue. You are all be invited. By the way, the place will be crawling with strippers. Oodles of them.
Because that event, however unlikely, would be cause for celebration. A depraved bacchanalia the likes of which this city will never forget. Because teams that pitch like that usually get cool t-shirts designed in their honor. Oh and they win the crap out of playoffs series.
I'm very interested to hear what other people think of these bullish projections. Do you put a lot of stock into them? They can't predict Jose Bautista-style breakouts but nobody can. In the case of Brandon Morrow, the projections suggest something we all know/believe: a great season lurks in those peripherals. Though I'm on the record saying things might get worse before they get better, I remain excited to see how this pitching staff shakes out.

Projectile Vomiting Numbers

Projection systems aren't without value. Much like advanced defensive metrics they can be useful if you go in with the correct state of mind. Don't pick and choose which numbers suit your preconceived notions but apply heavy dash of skepticism at all times. Sometimes the numbers don't add up or seem to make sense but you can't expect too much from (relatively) simple algorithms.
Below I took the three projection systems available at Fangraphs - including newcomer Rotochamp - and averaged them together with fan projections available on the site. None of the numbers are weighted to allow for Bill James' insanity or the simplicity of the system with a name so dumb I can barely bring myself to type it: Marcels. Take in the results and scroll down for my jaded commentary.
Please note Rotochamp (listed as RotoC) doesn't include a wRC+ projection and no way in Hell am I capable of those types of mathematical gymnastics. The Rotochamp people also exhibit the good sense to completely ignore Juan Rivera who, I am shocked to learn, now plays for the Blue Jays.

I'm not quite sure what to make of these Rotochamp people. Quite bullish in most instances but very conservative in others. Witchcraft is tricky, y'all. Let's go one at a time.
- I cannot say I have a good grasp on the expectations for Jose Bautista in 2011. Just about anything halfway decent is good enough, right? Even the most conservative projection noted here is still a fistful of house money, so let's just say 28-30 home runs is plenty and move on quietly.
- All systems agree: Travis Snider is the Jays second best hitter! I don't know whether to laugh or cry. Decent power numbers across the board but home run fluctuations due to playing time. Now let's all close our eyes and pretend his health record is somewhat awful as we cheer him into a meat coma.
- In spite of projecting Lind to play 8 days a week in order to amass more than 700 plate appearances, the Rotochamps are very conservative with Lind. 25 home runs? Sure, whatever. Just don't make so many bloody outs.
- If I told your three years ago that Aaron Hill would emerge as a 20-25 home run threat but no better than league average overall, no way you believe me. No. Way. But that is pretty much all he projects as. Scary. Miss u, line drives.
- League average offense from Yunel is more than enough. His glove makes the rest okay. I hope new manager John Farrell can get his walk rate out of the Canadian Customs lockup.
- Edwin Encarnacion is the EEnigma! As Ian the Blue Jay Hunter astutely points out, this is a man in need of a full time job. Ian has a money quote from Alex Anthopoulos regarding The EEnigma's breakout chances. The math nerds all agree: the power is not in doubt.
- That sure is a lot of stolen bases. No matter how many he swipes, too many Blue Jays fans (like me) are going to have a really hard time adjusting to seeing someone caught stealing over and over. Not that Davis is inefficient, but you can't steal tonnes of bases without going with some regularity. Science!
- Juan Rivera is a poor fielding Aaron Hill. Vernon Wells, in other words.
Thanks to Fangraphs for all the projection goodness.
