They ignore many fouls against Maxi too. Which is kinda funny since he's Argentinian and from CONMEBOL.I think people have just typecast him as "a CONCACAF player." He's young, talented, aggressive. I don't know if he complains more than average, but he's not really the "strong, silent, play-through-it" type either. And he can oversell legit fouls a little—not really simulation, but a degree of youthful overacting when trying to make the foul "stick." In combination, folks just don't cut him any slack.
Maybe I'm unfairly projecting r/MLS attitude about City onto the refs, but it seems to me that they whistle him like they're trying to put him in his place. Even Ring, who's just as aggressive, gets more leeway. (I say, completely without data to back it up.) Looks to me like it's a personal thing against Yangel as a "type."
In any case, that's at least what Chapman was doing yesterday, to my eye. The calls were inexcusable. Not about the fouls, or even game control at that point. Just a dominance display against a young player who got under his skin
Whatever it is labeled, there is a blatant bias against NYCFC with the non-PK calls.
