I know myself and others were a little confused on the new redshirt rule (allows a player to play in 4 games and still redshirt) and how it relates to the post season. There was some talk that you cannot participate in a post season game and still redshirt. I found out that’s not the case. A player can play in any 4 games (including bowls or post season) and still redshirt. This article references that fact as well. This made how a coach uses this rule much more interesting to me.
