Well, I care, but the issue here of a player not playing in the bowl game is really a fan's issue, not a player's primary concern.
Players, as said above, have to make their own decision. Since there are a bazillion bowl games, I get that they have very reduced importance now. So, does a player:
1. Play for better life time stats?
2. Play to show an agent/NFL team better tape?
3. Play for glory?
4. Play because they love the game?
5. Play for their teammates?
6. Play to whip the other team?
7. Play for the fans?
Not play because:
1. They have a serious/nagging injury that needs to heal?
2. Not want to keep practicing and wants to focus on the combine/draft?
3. Need some kind of medical procedure that they need more healing time?
4. Want to let the teammate behind them in the depth chart get a chance to shine/practice since they are not going to the NFL or are a first round lock?
5. Take some time off because of the ever increasing number of football games and the personal time commitment it requires?
6. Other random personal reason?
As a fan, we all want the players to put in 100% every game and play, but it's just not that simple.
So, I vote for "it's complicated/I won't burn a player that opts out save for the true quitter.
