admits to talking trash on the field and "never wanting to be mic'd up"
There's a significant difference between "In-Game" trash talking and "Pre-Game Warmups" tt. The problem here is that Witherspool went out of his way and interrupted the Saints' warmups in order to trash talk the players. This is unprecidented, and it is not an acceptable part of the football culture.
