Do I watch baseball? I cover the sport for a large metro newspaper.
Regarding Joba...you're an idiot because you suggested that the fluke situation of dealing with midges is more important to his success than his weight is. That is wrong. Joba has said he wouldn't be in the big leagues today if he hadn't lost all that weight. Also, he was considered top-three talent-wise in the draft but he slipped to the Yankees at 20-something because teams were worried about his weight. Why would teams worry so much abotu weight if it were a benefit? He was called another Sidney Ponson.
Like I said, he went from throwing 82 mph as a HS senior to topping out at 101 at age 22 because he shed 50 pounds. This isn't rumor. This comes from his high school and summer league coaches.
Concentration? Joba has performed extraordinarily well every step of the way with the lone exception being that midge game. His concentration was fine when he stared down Becket for seven one-hit shutout innings in Fenway and buzzed Youk for the hell of it again.
If you really believe the midges phenomenon proves he has concentration problmes or that he won't be a star based on that, you are an idiot. In fact, he is already a star.
You are right that baseball is a sport fat people CAN excel at (though, so are football and basketball). However, that does not mean fat people are better suited for sccess in the game. Additionally, the issue was longevity, and you have still failed to provide a list of pitchers 300 pounds heavy who performed as well at age 30-35 as they did at 25-30. I didn't dismiss Wells. I said he's an exception that proves the rule. Apparently, you are nto familiar with that phrase. The Fielders are hitters, not pitchers.
The first link you posted is irrelevant because it deals with SINGLE seasons. That's not the issue. The second link is interesting particualry because of this line "Survival rate is simply the percentage of 25 year-olds who were still pitching at 32."
Does 32 strike you as old for a pitcher? It shouldn't. Not by today's standards. Not when Mike Mussina wins 20 games for the first time at age 39 (and he's pretty small, by the way). Also, that analysis doesn't account for body fat, just total weight. Body fat, of course, is the issue.
