By definition, the word "obnoxious" used as an adjective means something that is extremely unpleasant. Luckily for sports fans everywhere, there are plenty of those on each professional team ready to speak or act out just when we least want them to.
Every NFL team has at least one of these types of people. He is basically that person who talks too much and can never back it up with his play or results.
Those individuals essentially do nothing but hurt the team with their antics and sometimes even interfere with their respective teams chemistry.
Some of the choices are not limited to only players that are on the team, but people who are working for the team whether that is the coaches, management or owner.
This is not to say they are awful athletes who deserve to be fired, but just that they are those individuals whom fans are starting to get sick of or just over. They may have some redeeming qualities, but for now, they do not outweigh the negative affect toward them.
