I know one commentator spoke about the thrill for a QB to finish a big game, for his own enjoyment. Kind of like a pitcher going for a no-hitter even though his pitch count is getting high.
Personally, I think there was a time when if a team was down by 20 points in the fourth, you'd let your backup get some reps and valuable playing time. It was good for the league and kept your starter healthier. Less wear and tear, also. Now, it seems that teams are hoping for that three touchdown miracle. Sure it happens sometimes, but if you are being outplayed, your starter is struggling, or there is only five minutes left, use the opportunity to develop your backup. personally, I would have liked to see Willy come in for the last five minutes of the Hamilton game just to help him find his game form again in case Nichols gets hurt.
Maybe bonuses should just be on wins, not yards or playing time. Healthier for the QB and the team
Always my team, even at their worst.
