When you do a lot of work with projections and make a lot of predictions, one of the hardest things to get used to is the amount of times you'll get things completely wrong. Every year, there is a handful of players for whom events don't even out and they end up missing their projections by a mile. There are a lot of reasons for a player to be disappointing, from mechanical flaws to injuries to the most frustrating reason: "dunno."
Looking back at the 2011 ZiPS projections, we thought we'd take a look at who failed to meet their projections by the biggest margins, examine what went wrong and look ahead to the 2012 season.
Projected OPS: .922
Actual OPS: .569
It seemed like a match made in heaven: one of the most consistent sluggers in baseball getting to DH and play in a solid hitters' park. It didn't quite work out that way, with Dunn missing his projection by a greater margin than any player ZiPS has projected in the last decade.
The only consolation is that while there were good reasons to not be confident about Dunn down the road, nobody really saw a top slugger like Dunn slugging .277 when he was 31.
Going forward, it's hard to have any faith in Dunn. A decline of this magnitude is almost entirely unprecedented in baseball history. Without Dunn having lost an arm or something similar before the 2011 season, there's no easy explanation for his downfall. Dunn could come back in 2012, but after last season, both the White Sox and fantasy owners need to be skeptical. Even if Dunn has a major comeback, it's going to be mostly in the form of home runs.
2012 projection: .209/.340/.429, 26 HR, 76 RBIs
