In a ton of Miguel Cabrera topics, I've seen at least 40000000000000000 posts per topic about his weight, does it really affect him that much? It doesn't seem to be affecting him hitting but would his fielding really improve if chubs doesn't steal from the cookie jar too often? Or does he just suck as a fielder. There have been plenty fat players in baseball that are/where great players: Babe, Gagne, Fielder... you get the point (Fransisco Cordero's also 235 pounds). How fat is too fat?
First, I think it's self-evident that excess weight will affect elements of his defense- think about "range" for starters - as well as things like his value on the base paths (although he has a pretty bad SB ratio for his career) and etc.
Next, people bring up people like Ruth, Gwynn or Fielder - unique players with unique body shapes - but the vast majority of baseball players a.) do not have their talent and b.) do not have their body shape. Yes, John Kruk famously said he's not an athlete, he's a ballplayer - still, though, most ball players are in pretty decent shape, and those who are out of shape tend to either have one limited/unique skill (Matt Stairs) or suck (Lenny Harris) or pitch (Bartolo Colon, who also falls under "suck").
So is Cabrera the Babe? Well, first, we can say that it just might be affecting his hitting - while Cabrera was still an elite-level hitter last year, his EQA dropped .012 points (from .333 to .321), and he hit a few more HRs but dropped a larger amount in 2B, not a great indicator going forward. Besides this, his value takes an instant hit if he eats himself off 3B to 1B, just by nature of the defensive spectrum - plus, he isn't really all that good at 3B right now, apparently.
So, essentially, I think it's an easy answer: any fatter would be "too fat" in one sense (overall value), all corner-case comparisons to Tony Gwynn at age 35 aside. This does not mean he's not an elite talent coming off his age-24 season - he's HOF-caliber. He's also Friendly's-caliber, and this should not be tossed aside because Babe Ruth drank whiskey and smoked back in the 1920s - those kinds of comparisons suck.
