Five tips for winning big in daily fantasy

 One man's injury could be another man's gold mine: When an expensive player goes down due to injury, it can open the door for you to cash in big with his cheaper replacement.

 Matchups matter: If a WR will be paired against an elite CB, you may have better luck going with the team's No. 2 WR.

 Mix and match: If you're looking to make big money, combine one or two studs with some sleepers who could cash in big so your lineup isn't like everyone else's.

 Do your research: Coaching tendencies, real grass or turf and weather are just the tip of the iceberg.

 Stack 'em: A popular daily fantasy sports strategy involves "stacking," where you pair a QB with a WR, TE or RB teammate.

Here's a quick rundown on daily fantasy sports: Most DFS formats use a salary cap, where players are allotted values and you must stay within your budget while building your lineup. Once the lineup is set, the player's real-life performances earn you points.
