LeGarrette Blount
It’s never acceptable to attack another athlete even if they say something very insulting. Yes, it may be tempting to teach them a lesson but ultimately it backfires. That’s because it will lead to a suspension and hurts the player’s team. Unfortunately, Blount didn’t consider this when he had a rush of blood in 2009.

Boise State handed the Oregon Ducks a tough loss. The Broncos’ Byron Hout trash-talked Blount in the middle of the field. This was bad sportsmanship because it was disrespectful. Then Blount punched him straight in the face. Hout received a brutal lesson while Blount got a lengthy suspension (via NBC Sports).
