On Wednesday, Buffalo Bills wide receiver Stefon Diggs became the latest wide receiver to land a mega-contract extension.

Diggs is reportedly signing a four-year extension worth $104 million. It includes $70 million in guaranteed money.

The guaranteed money is the important part of the contract. Everything else in the deal is essentially mythical.

Diggs' extension is the third big wide receiver deal we've seen this offseason. Davante Adams and Tyreek Hill received mega-extensions (with new teams) earlier this offseason.

Adams, Diggs, and Hill all received similar contracts in terms of guaranteed money. Adams got $65 million, Diggs got $70 million and Hill got $72.2 million.

This is the market now for a top wide receiver.

Which means this is basically what the Tennessee Titans will need to pay AJ Brown to keep him in Nashville.

But the longer the Titans wait to extend Brown, the more expensive he's going to get.

Seattle Seahawks wide receiver DK Metcalf and San Francisco 49ers wide receiver Deebo Samuel are a couple of the other young elite wide receivers waiting on extensions right now. It stands to reason that the last one to sign an extension will get the most money.

That's because the last top wide receiver without an extension will be a player that other teams are calling about.

Teams like the Green Bay Packers and the Kansas City Chiefs could use a true No. 1 wide receiver. Even a team like the Chicago Bears, a franchise going through a rebuild, could choose to make an offer for Brown.

If Brown is an in-demand player, he'll have some leverage. The Titans know they can't trade Brown — the fan reaction would be extremely negative, plus Tennessee would be a worse football team without the former Ole Miss star. But if other teams want Brown, he knows he can push his price up quite a bit. At the end of the day, Brown knows he'll get his money — whether it's from the Titans or another NFL franchise.

It's going to be the Titans, though, that pay Brown. General manager Jon Robinson doesn't let key players leave in free agency. And with quarterback Ryan Tannehill's time in Nashville likely coming to an end soon (maybe after the 2022 season), there will be some salary-cap flexibility for the Titans to make a big deal with Brown.

This could be the biggest contract that Brown will ever receive in his career. Trying to get the biggest deal possible is a wise move on his part — he deserves to get paid.

The Titans, however, would've been smarter to get this deal done sooner. The longer they wait, the more guaranteed cash they'll have to give Brown. Tennessee doesn't want to end up in a situation where they have to give Brown over $80 million in guaranteed money. But that's the direction this contract negotiation is trending toward.
