I expect the suspension to be reduced to 1 game, but here are some differences between this and the AJ Green fight.
It's the 2nd straight year the two have fought, going back to the gold chain incident.
After being separated, the two re-engaged in the fight with more punches thrown.
It wasn't in the middle of the field, but spilled over to the sidelines where media and other non-football players were with at least one official getting hurt. Talib threw Crabtree's helmet at him and could have hit a non-football player.
In any league, if you get off the playing field and go anywhere close to where non-players can get hurt, the suspensions are going to be higher.
