I'll admit I'm somewhat of a sabermetric mark, so my views are slightly biased. However, I've come to realize that many of the traditional stats have some ridiculous flaws or don't tell the whole story.
Take average for example. While it is nice to have a .300 hitter, if the guy only has an OBP of .347 (or some other random number) then I'm not gonna want him as much as a guy that hits .270 but gets on .380 clip. Sure, that extra .03 on the BA looks nice, but a higher OBP gives you a better shot to win games.
Wins for pitchers is another stat that I've come to terms with is highly overrated. A guy can go 5 IP and let by 5 ER but if he's up 6-5 and the bullpen closes it out, he'll pick up the win. Conversely, a pitcher can go 8 innings, give up 1 an unearned run (let's say by a dropped sac fly in the 2nd) and picks up the loss because his team couldn't score for him or play reliable defense. Its not the pitchers fault they can't score and that the guy dropped a catchable ball, yet he's looked as the goat of the game because he's given the loss. Its an awful way to measure how good a pitcher is, and I'm never going to change my stance that the best pitcher is the one with the most wins. While some years the best pitcher does have the most wins (such as Verlander this year) other years guys just get the unfortunate luck of landing on a bad offense (Greinke in 09 and Hernandez last year). WHIP, ERA (although it has slight flaws is quite effective), ERA+, IP, OBA, K/9, BB/9, HR/9 are a much better measurement of who's the best (when combined together).
(Sorry I just went on a tangent there. Just needed to give my opinion on sabermetrics).
Have I just not paid close enough attention over the years or is MLB just making up new stats now? MLB Network was just talking about how Jose Bautista led the league in WPA (win probability added). What the hell is that? They explained it but I was only half paying attention. Sounded like a bogus stat to me. A stat made up for the sake of discussion that doesn't have anything valid to support it. Same with WAR. I'm happy to admit I may just be missing something here but I think these analysts are really reaching to make up some new numbers for players.
I don't know if you were looking for an explanation, but I'll try to give as simple of one as I can.
WPA goes like this - a player hits a HR in the first inning to give his team a 1-0 lead. His WPA will go slightly up (ever so slightly) due to the fact that theres still 8 innings to play. The game gets tied up and another HR is hit in the 8th inning, giving that players team the lead for good. His WPA will go up much more significantly, since there's only an inning left. While both score 1 run and are at equal value, the one hit is hit in the 8th has a higher WPA due to the scenario it is hit. Somewhat like a 'clutch' meter, if you will. The HR in the 8th gave that players team a higher probability of winning then the 1st inning HR, so of course his individual WPA is higher.
Not a bad stat when you think about it. The players with a higher WPA normally are more vital to their team. Look at the AL hitting leaders in WPA, 11 of the 13 there were on the MVP ballot (Abreu and Hamilton I believe weren't), and they were pretty much in the order of how WPA was distributed (except Ellsbury was voted above #1 and #2 in WPA). It's obviously not the be all, end all stat (none are) but I think it helps determine who's helped their team the most. A guy that hits a 2 run double to give his team a one run lead is more helpful then the guy that hits a 2 run double when they have a 10 run lead.
Kemp was awesome, but he didn't help his team win, because his team didn't win; they sucked.
That's an ignorant statement right there. The Dodgers were slightly over .500 (83-79 I believe) and while they weren't in playoff contention they would've been a 70 win team, at best, without Kemp (and Kershaw). That was about as two man of a team as you'll get. I didn't realize Kemp should be blamed for his teammates sucking, even though he spent half his season playing in a pitchers park and a played much tougher position at a more successful rate of defense. He also didn't have another bat behind him like Braun did with Fielder. I realize value is subjective, but to say he didn't help his team win is just straight out wrong.
That's the problem with MVP voting. People think just because a guy isn't on a playoff team he isn't valuable. In fact, I might go the exact opposite, since most of the time the guy on the playoff team has a bunch of teammates that have great seasons. Look at the winners this year
Verlander had Cabrera, Avila, Peralta, Martinez, Boesch (for most of the year), Valverde, and Fister (for the last 2 months) who were all just as influential. Was Verlander the best player, yeah. But there's 6 guys right there (combining Boesch and Fister as one) that were just as important in his teams success.
Braun had Fielder, Weeks (for part of the year) Nyjer Morgan (who helped out a lot on D) and a pretty strong pitching staff and closer. Thats 8-9 guys there, and again they were just as important. Was Braun the best, yeah, but those guys were just as important.
Bautista on the otherhand had... Ricky Romero and... Brett Lawrie for a few months? That Blue Jays team wasn't much special (aside from Bautista) yet they still managed to be .500 in the best division in baseball.
Kemp had Kershaw, and that's about all who you could say was a contributing factor. Their offense blew and their pitching staff wasn't more then maybe slightly above average.
Bautista and Kemp had the best seasons in their league, yet they aren't getting recognized it because their teammates couldn't help them out enough. Just seems like a dumb way to determine who's most 'valuable', to me.
EDIT: I'm not trying to say the MVP should go to the best player on an average team. I'm saying it should go to the guy who gave his team the most value and where would they be without him. The Tigers won the division by 14 or 15 games. Would they have still won the division if he was only average, probably. Same with Braun. They still probably would've made the playoffs. Would the Dodgers or Blue Jays have cracked the 80+ win total without Kemp or Bautista, probably not, since there's not as much talent around them.
