In order to win, you have to know nearly everything going on in the National Football League and have the latest FF news to make sure you make the moves that best fit your team. Throughout the season, injuries are going to be one of the most important factors for your fantasy football team. For example, if you have a running back on your team who is having a great season, but you are not using as one of your starters, he still holds a lot of value. And if another player gets hurt, you need to know right away who his backup player is to see if that may be a good addition to your team now that his playing time will increase.
A sudden injury may create a need for one of your opponents, and open up a trade opportunity for your team. If you have a great running back on the bench and need a wide receiver, you could possibly trade your RB to your opponent if their starting RB gets injured.
Granted, a Fantasy Football team has a lot to do with picking the right guys in your draft, but in order to win you must know everything going on around the league to see how it impacts your teams, and your opponents teams.
