There's a big difference, and you're swinging quite a bit here on a hyperbole. Nobody is a perfect human being (though Mix does have perfect hair).Do you think all the guys on the team now are perfect human beings? You're delusional if you think that's the case.
I don't know much about John Terry and him being a good person, but the amount of people that say he's a terrible human being kind of tells me I probably don't want him on our team. And then as simple as looking on his wikipedia page and seeing separate categories for Legal Issues, Extramarital Affairs (which included one of his teammates girlfriends), and Racial Abuse Allegations is enough for me to get a decent idea.
Now I haven't looked at the wikipedia pages for all of our guys, and I'm sure for quite a few of them, this level of detail wouldn't be available as outside of the NYCFC realm they aren't well known, and their missteps probably not as well documented. But I don't get the feeling they fall to the John Terry level.
