What’s about to happen in the NFL world? The only way I can describe it: outrageous ridiculousness. That’s right, outrageous ridiculousness. This will be an unprecedented stretch of trades, signings, cuts and practices. It all starts tomorrow, with facilities opening all over the league.

For the first three days, teams will be able to openly negotiate with, but not sign, unrestricted free agents. This is something that has been talked about in the past but has never happened until now. It’s a cool idea and a way to prevent teams from tampering. Expect it to become commonplace in the future.

Here’s a look at what’s coming next:

Upcoming schedule (Via a brief issued to agents today)

Tuesday, July 26: Facilities open; trading begins; clubs may sign all rookies, and negotiate with but not sign all other players at 10:00 a.m. ET.

Thursday, July 28 at 4:01 p.m. ET: Clubs may waive or terminate player contracts.

Friday, July 29 at 6:00 p.m. ET: Unrestricted free agents can be signed; contracts can be renegotiated; signed rookies may participate and have protection if injured.

Thursday, August 4: New league year begins if CBA is ratified (can happen sooner if possible); all teams must be under salary cap; newly signed unrestricted free agents can begin practicing.
