While the champions are dancing on the field celebrating their win, don't get too caught up in the party. Because when the gun goes off to end the Super Bowl, the off-season officially begins. GMs can begin submitting their trades via the online TeamManagement interface.

All around the league, GMs are hunkered down in their offices manning the phones. The first couple of days of the off-season might not see any trades, but don't let that quietness fool you. Behind the scenes every GM is involved in negotiations that could bring his team a chance to replenish his team with fresh talent.

Almost every season you will see nearly %75 of the trades being pulled within the final 24 hours of the trading period. Its all about timing. Pull a trade too early or too late, and you might not get enough value in return. Its all about timing.

All trades should be submitted through the online TeamManagement interface. Trades can include any players* currently on your roster and any draft pick within a four year period (upcoming draft and three future draft). Trades are approved once the second GM confirms the trade.

On the night of the College Draft, trading is suspended from 6pm to 10pm et. GMs can still negotiate behind the scenes, but they will not be able to access the Trade Submission interface within the TeamManagement area until the draft is over.

The trade period ends at midnight on Thursday of week three. Once the clock strikes midnight, trading is over. So 11:59:59pm is the final allowable timestamp for a trade.

* Except players that you've just signed in the Free Agency Market. They must play at least one season on your roster before you can trade them.
