The guy who just signed an extension and cut down his antics this year? Doubt it.
in all seriousness wacky, peters was suspended for one game, and since then went on an absolute rampage on the field (even tackling ball carriers!), without any negative incidents on or off the field. his numbers are staggeringly good, like unbelievably good, and there are numerous positive stories about him doing good work in his community, his teammates seem to love him, etc.
when people resort to assuming it's about the kneeling, it's only because they're running out of other plausible reasons.
