Yahoo ranks the players as either A, B or C players. A players are the cream of the crop guys and so on. You pick 2 A players, 4 B players and 2 C players each week. You can only start 1 A player, 2 B players and 1 C player to get points based upon what they shoot. You can only start a player (get points from them) 10 times a year (tournaments) This keeps people from starting Tiger every week he plays. But if you start a player and he misses the cut you can switch him out with another player you selected that week and continue to get points. But switching players burns a start for him as well. Best rule of thumb is to set your starters and leave them. If you have to switch players due to missing cuts make the new guy not a too good one as you may want to start him another week and you don't care if you burn a start on a average player
