Maybe a TD or sack enables a veteran to hit an earmark or make the PB but it doesn't happen because they are benched for backups. I know teams bench starters if they are in the Playoffs but that is a much different situation. Just playing devil's advocate here, something to think about if you are a veteran on a bad team. I would not want to lose a big incentive over a draft pick. I would be quite upset about it and would want to be traded if I missed it knowing I could have likely achieved it in two benched quarters.
