Starting this season, the league is getting more strict with penalties. The first time that you miss picks during the season you will use last week's picks and receive half the points. That part hasn't changed but what has changed is that everytime after that, you will receive 0 points.
Missing three weeks in a row and five times for the entire season will still get you removed from the league.
its by whatever series you are in. If you miss 5 times in the Cup series, you are booted from that series. If you miss 5 in the Nationwide series, you are booted from that series.
