to me the biggest drawback in FAAB is when you get news that a player is going to miss some time either that day or all week and you aren't able to pick up a player to replace him. Even if it is a weekly league and you are looking just at Mondays before the first game of the day, you are stuck with just the players on your roster to start that week. Another drawback is if you don't get the player you bid on,you either have to have a bid on a lesser player as a backup or do without till the next bidding. The most common bids are daily, weekly and twice a week. FAAB does eliminate the rush to the computer to pick up the guy who just got handed a starting job, but it does have its limitations too.
