We are just one week away from the start of the new NFL calendar year, and it's an exciting time for Dallas Cowboys fans. The franchise has adopted some new approaches to the offseason to kick off 2026, and after weeks of promising to "bust the budget,' Jerry Jones better put his money where his mouth is.

The 2026 NFL calendar officially kicks off on Wednesday, March 11, at 4:00 p.m. ET. When the clock strikes four, teams will be able to put pen to paper to begin signing their free agent class.

But while deals are not official until Wednesday at 4:00 p.m., there are some behind-the-scenes shenanigans going down for the two days leading up to the new league year, which is referred to as the "Legal Tampering Period."

This year, the legal tampering period will begin on Monday, March 9, at 12:00 p.m. ET. That's when teams can reach out to players and their agents to gauge interest and begin the negotiation process.

When legal tampering begins, reports will start pouring out from league insiders about unofficial deals and agreements between teams and the players.

That will be our first look at the caliber of player Jones and the Cowboys are targeting on the open market, and just how honest Jones was regarding the team's budget, so let's hope he follows through.
