Kwon Alexender showed no mercy for his former teammate and it ended up costing him big time. The San Francisco 49ers linebacker didn't hold back when going after Tampa Bay Buccaneers quarterback Jameis Winston, tackling him as he was sliding down with an absolutely brutal helmet-to-helmet hit that led to his ejection from the game.
Stuff like that has no place in the game of football. It's perfectly acceptable to play the game hard, but going straight for the head can leave players with lifelong injuries.
Hopefully the ejection shows Alexander just how dangerous that type of hit is.
