Geno Smith seemingly isn't a bad person, but the former Seattle Seahawks quarterback does have a bit of a temper. It got him in trouble with his first team, the New York Jets, when a teammate punched him in the face. With Seattle, Smith could cause teammates to tune out during games because of his volatility.
This isn't anything that couldn't be viewed on a broadcast. Smith might be seen brooding on the sidelines after a negative play or demonstrably discussing something that just happened with a teammate. As the quarterback, he was going to automatically be a leader, but was he a good one?
