I'm annoyed as just about anyone we didn't get Fowler but the "we are worse than last year" posts are getting to be.
Sure if we look at the talent level of the team Morales and Pearce doesn't replace EE, Bautista, Saunders, Benoit, and Cecil. EE was a 4 win player last year, Saunders and Bautista a win and a half, Cecil and Benoit half a win each. That's 8 wins replaced by 2 win Pearce, and 1 win Morales, we're 5 wins worse.
However when you look at their actual impact on the field you'll notice that due to bad sequencing particularly from Saunders and Cecil you don't need to nearly make that much up. This is where WPA comes in. It doesn't tell you how good the player is and how good they will be moving forward like WAR does. It tells you how much they impacted their teams chances of winning. A player with a high WAR but bad WPA was a good player but good in low leverage spots, bad in high leverage. And the reverse a low WAR, high WPA player was bad but good in important spots.
EE has a WPA of 1.77, therefore his apperances at the plate(defense not included here in this stat) contributed to 177% increase in the Jays chances of winning. Essentially a full game won, and another 3/4 of a game directly from EE's doing. Jose was 1.38. Benoit was 1.18. So that's 3 guys who contributed to winning, they did their good in important spots. Saunders and Cecil however, despite being a positive contribution if we remove context from the situation, both contributing positive WAR's were brutal situationally. We might not remember now but Cecil blew so many games at the beginning of the year(you probably remember that), and Saunders was just about the worst player in baseball history in high leverage spots. I remember reading an article late in the year, if his 30 highest leverage spots he contributed positively in exactly 1 of them.
Cecil was -1.68, Saunders was -1.52 , also interesting to note, Dickey was -2.10. Despite not being a major guy WAR wise , and you figure easily replaceble by Liriano he was actually a huge strain on the team and that replacment should actually gain you a couple wins.
There weren't any other players gone that were major contributers. Goins and Barney were both worse than -1, but both primarily as backup infielder and 1 of them will have that role still(presumably Barney)
So overall through those 6 players out you're losing a combined contribution of -0.97. That's right, you're actually losing a loss by subtracting those 6 guys.
Now it's important to note that in this stat 0 isn't replacement level like in WAR. Every percentage point gained by the hitter is lost by the pitcher and vice versa so 0 would be average.
So if we replaced these 6 guys with league average players and everyone performed the same way we'd gain a win. Pearce and Morales are fairly average so far. Probably above average actually.
Also important to note, this stat tells you the impact a player had on the teams probability to win games in the past. It's based on situational results. Sisutations change. Donaldson might hit the exact same number of homeruns next year but it won't be in the same spots. He could be just as good of a player and his WPA go up or down, that's just the luck of clutch hitting which isn't really a skill at all.
Also important to note this doesn't include defense. Defense is sort of included in pitcher WPA I guess, except for errors, because a guy who can't get to a ball that results in a single is a bad result for the pitcher and hurts his WPA. Bautista and Saunders, not exactly good defensively so losing their defense could also improve our poitchers WPA slightly.
So yeah that's basically my very long rant about how we might not statistically be worse next year. It sort of revolves around the though that we were to some extent unlucky last year and a slightly better team if Saunders, Cecil, and Dickey weren't situationally horrible and replacing them with guys who are just average is in turn actually a huge gain.
But yeah, still annoyed we didn't get Fowler like a lot of the rest of you, just some food for thought.
