For the first time in NFL history, the league allowed legal tampering in 2013. Essentially, teams could talk to the agents of players on other teams. However, they could not visit with the player, sign the player or even agree to terms.
This new rule was likely instituted due to how widespread tampering is. Judging from this weekend's action, it would appear this rule allowed teams one last chance to negotiate with their own players by using the leverage they have in talks with players from other teams they could sign to replace their own.
We've heard rumors of what players are likely to be the highest paid once free agency begins on Tuesday. It wouldn't be a surprise if the second wave of free agency actually saw more action than tomorrow because teams don't have as much money to spend with only a limited increase in the salary cap for 2013.
Every year, there are players who sign record-breaking contracts that leave many around the league shaking their heads. This year will be no different.
Here is a look at five free agents that are sure to be overpaid and why teams may regret their decision a few years from now.
