Players who are not part of your starting lineup remain on the bench. Benched players don’t earn points, unless they are auto subbed back in.
Players on the bench (or eg. “in the bus” in case of Fantasy Cycling) are part of your overall strategy. Benched players this week, could become starters the next week, depending on the opposition strength and form.
Fantasy Sports games that make use of a bench usually allow only a small number of transfers during the season. Or they deduct points for each additional transfer.
