Welcome to the Monday edition of The Cooler. I was going to make a joke about humidity, but it was terrible. So on with a few items:

*We've reached the quietest time in the NFL. Minicamps are done, but training camps don't start for more than a month. The content, though? It never really slows down.

It's not like ESPN, SI.com or NFL.com just put up a blank page on the NFL portions of their web sites that say, "Page not found. Check back next month."

Bucky Brooks seems to acknowledge this with a recent piece for NFL.com about the best wide receiver groups in the NFL. He used a bold statement by Browns receivers Josh Gordon and Jarvis Landry — that Cleveland has the best receivers in the league. Cleveland! — to explore the question. The beauty of the list is that nobody can disprove it for months. They can only argue about it.

That said, Vikings fans should note that Brooks — a former NFL player — picks the purple as having the best group of pass-catchers in the NFL. He writes:

"It's no coincidence Kirk Cousins picked the Twin Cities as his new home. Like the rest of us, he saw the Vikings' WR corps torch defenses in 2017 with a journeyman QB2 at the helm. Adam Thielen and Stefon Diggs are spectacular route runners with outstanding stop-start quickness, wiggle and playmaking ability. Each guy is capable of taking over a game as a lead receiver, but it is their collective ability to create headaches for opposing coaches that make them the top pass-catching tandem in football."

Maybe it's time to stop thinking of Thielen (undrafted) and Diggs (fifth round) as scrappy overachievers and start thinking of them as the best of the best?

*If you run onto the field of play during any sporting event, you run the risk of many bad things happening. But it stands to reason that the idea is particularly bad in football, where you potentially will have to elude not just security guards but also fully padded players who are trained in the bone-crushing arts.

That windup is not just idle chatter. It is a setup for what happened in a CFL game featuring the British Columbia Lions recently. Here is your deterrent for every trying something so stupid:

*And finally, the World Cup has been full of underdog surprises so far. The best example came Sunday, when Mexico defeated defending champion Germany in group play. How big was the 1-0 victory back in Mexico? The force of the celebration following Mexico's lone goal in the match registered as a small earthquake.
