There are plenty of fantasy “mistakes” that can sneak up on both rookie and veteran owners.  Here’s a quick list of some common situations that owners should avoid.

Don't over manage – Some owners are always shaking things up, but that can do more harm than good.  Constantly turning over your roster is a dangerous game to play against the law of averages.

Don’t fall asleep – While some owners over manage, some fall asleep at the wheel.  Join a league that suits your activity level and remember that you have a responsibility to the league to manage your team competitively.

Don't Panic - It seems to be a familiar theme in the first few months of the season, but, too often, many owners panic and release players after a poor start.  Figure out a way to keep the slumping player on the bench until he can work things out before considering an outright release.

Don’t waste time – Don’t waste your time by offering silly trade offers.  Come up with something fair, and by all means, put a note explaining why you are purposing the trade.

Don’t ignore leagues fees – There’s always someone that the poor commissioner has to track down to get league fees paid.  It’s just not fair to the rest of your league – be an upstanding fantasy citizen.

Don’t assume – My grandmother once warned me never to ass-u-me.  I’m sure many of you heard the same advice.  Don’t assume a player will be healthy when his DL stint is up, don’t assume you will acquire a player during waivers, don’t assume you can always “trade for it later.”  Basically, take a cautious approach and have a backup plan.
