Your fantasy football draft is over, but your work isn't done. Active managers win more often than casual ones, as Mike Clay explains. In a 2007 league, his brother Matthew drafted a stacked team but rarely checked it, losing in the semifinals. Clay, who started 0-7, made trades and won the title.

To avoid a similar fate, use the trade and waiver markets. Understand your leaguemates' tendencies, like overpaying for hometown players or overreacting to Week 1. Team-building is an ongoing process, so don't be too content with your roster.

Stay active and tinker with trades and waivers to maximize your chances. Success isn't just about the draft; it's about managing your team throughout the season.
