Fantasy football is wildly popular because it's a) easy to manage, taking only a half hour of your time each week to get up to speed on the previous week; and b) totally inclusive, inviting players of all levels; and c) transient and completely matchup-based. Far less popular, fantasy baseball is a much more intimate undertaking. With games played nearly every day for six months, you develop a "relationship" with the players on your team, making it even more important to be comfortable with those you draft. To ensure you'll enjoy your team all summer while finding fantasy peace of mind, I've cobbled together a list of Eight Do's and Don'ts that can be applied to all types of leagues, whether they're one league or mixed, head-to-head or rotisserie style. Get familiar with them going into your draft and you should come out in great shape for 2010.
