Geno Smith has seemingly never been afraid to speak his mind. This has sometimes gotten him in proverbial hot water, both with teammates and fans. The former Seattle Seahawks QB1 was shipped to the Las Vegas Raiders this offseason, apparently in part because of his lack of leadership skills.
Smith could get angry when mistakes were made. Sure, he got punched by a New York Jets teammate early in his career, partly because of Smith's temper, but 12s could see how Smith reacted to bad plays on the field with Seattle.
He might have accepted blame a bunch for whatever happened on the field after a game, and that's fine.
