In the NFL, one word that often comes up regarding potential free agents is tampering. For those who aren’t familiar, it is when a team or person tries to convince a player who is under contract with another team to join their team without the player’s current team’s permission. This practice became so blatant a few years ago that the league had to institute a legal tampering period before free agency so teams could begin negotiating. Anybody caught violating this rule would get slapped with severe penalties.
