He is right on prioritizing family for sure but he is also in a profession that gets 4 or so months off a year and, in his particular case, gets to retire by 40 with a net worth over $100 million. His irreverence towards the game itself is very telling through his past quotes; he talks about it like it's a blue collar job or something that he hates getting up to do in the morning.
Out of the many long-terms deals Arte has handed out that busted, Rendon is my least favorite player of them all. Hamilton is close but that guy had serious demons he was trying to deal with, not that it absolves him but it is at least offers some kind of explanation. Pujols certainly respected and cared about the game, he was just in denial of his diminishing skillset and potentially lied about his age. Rendon, on the other hand, just seems like kind of an overall douche. His memorable moments for me are fighting an A's fan, fighting the Mariners with a cast on, and hitting a home run from the left side of the plate in a blowout. He has also become pretty much universally hated by MLB fans. Sort of like Rob Manfred in calling the WS trophy just a piece of metal or saying the A's fans can just become Giants fans, it leads to questioning if he gives two shits about the game/league that has given him and his family a lot of financial success.
