A lot of baseball people/writers seem concerned about his size. Prince Fielder posted his last all-star caliber season at age 28. After that, he never was over 2 WAR. Pablo Sandoval was never overly good, but he certainly seemed to dive down from career numbers at age 28. That could be at least in part related to his move to Boston, and contract security leading him to care less and eat more. I struggle using guys that played in the 2000s as comps because they could very well be juicers. Ortiz, Howard, Migeul Cabrera, Carlos Lee...no proof but I'd rather avoid them as comps, especially Ortiz. Point being though, it will be pretty critical for Jr's longevity to watch his weight. On a side regarding weight, some of those drastic tail-offs make you wonder if we should look to trade Aguilar sooner than later before his value plummets.
