I didn't want to prejudge Pablo, but that doesn't mean there was never going to be a time to judge his effort. Pablo Sandoval's offseason efforts culminated in him playing his way onto the bench. It's the sort of thing that can happen to anyone -- IF they don't take care in the offseason. The responsibility for not taking care is his. He needs to eat the blame for the condition he showed up to camp in and how it affected his ability to do his job. No one else would be able to evade that responsibility, Pablo shouldn't either.
It's not about being fat. I actually seem to remember a couple players actually playing their way into the doghouse because they worked out too hard and came into camp so musclebound it affected their mechanics. It's about not showing up ready to do the job you are contracted to do. But either way, when it was time to get to work Pablo was clearly not ready, whether he planned to get back into shape as the season rolled on or whether he just didn't care at all doesn't matter. He was caught absolutely flatfootted by Travis Shaw's powerful challenge to his job this spring and had no ability to respond, and when he tried to respond by upping his game his poor offseason preparation exposed him to injury.
That's the bottom line, that's not me casting aspersions on Pablo's character, that's the culmination of what we have seen and can directly observe. And for a professional ballplayer who makes millions and whose #1 offseason job is to be ready for the season, it's absolutely, totally unacceptable. No organization should be willing to tolerate that kind of sloppy work from a highly compensated professional, and any organization receiving that kind of sloppy effort would look elsewhere to get the work done to a standard they find acceptable.
