The Kansas City Chiefs trading for Stefon Diggs? What year is this?!

The Chiefs are doing all they can in an attempt to return to the Super Bowl this season while of course hoping to flip the script from the end of last year, when KC lost to the Philadelphia Eagles in Super Bowl LIX 40-22 and failed score a point in the first half.

Patrick Mahomes is putting in his work. They believed they’ve bolstered the offensive line. Travis Kelce has lost 25 pounds. And the receivers room seems loaded with a host of guys who can fly … and who can play.

And yet …

A website called Last Word On Sports thinks the team could trade for New England Patriots receiver Stefon Diggs. And when you review their reasoning?

You realize that not even the website itself believes it.

“The Kansas City Chiefs don’t need another wide receiver this upcoming season, but it doesn’t hurt to continue building the depth,” they write. “Rashee Rice, Xavier Worthy, and Marquise Brown will likely be the main contributors to Patrick Mahomes’ offense, but Diggs could complete this package deal to a real fiery unit.

“If any team can get an athlete back in the right mindset from off-field issues, it’s the Chiefs.”

So … KC “doesn’t need another wide receiver” … but should trade for the troublesome Diggs, who just signed a three-year, $69 million deal with the Patriots?

If KC wanted him, why didn’t the club just sign him outright when he was a free agent?

What the site is ignoring about Diggs – who to his credit has a career of 10,491 receiving yards and 70 touchdowns and who used to be a magnificent if polarizing talent – is this: He’s now a 31-year-old receiver coming off a nasty knee injury who too often “does as he pleases” …

As New England just found out when he missed a bit of offseason workouts following the viral video from Memorial Day weekend that showed him handing an unidentified pink substance to a group of women on a boat.

“Obviously I want to be as candid with you guys as possible,” Diggs told reporters after Tuesday’s minicamp practice at Gillette Stadium. “I kind of have a thing where I don’t talk about my personal life with people I don’t know personally. I’m pretty sure everyone here are great people, but I keep my personal life personal.”

This sort of junk used to be the Vikings’ problem before he forced his way into a trade to Buffalo, and it was the Bills’ headache until last year when he moved to Houston.

He’s now on his third team in three years. And there are reasons for that.

In the end, not only do the Chiefs not need a receiver … they don’t need this particular receiver bringing to KC his age, his injury, his attitude, his baggage and his baggie of pink pills.

Otherwise, though, it’s a heck of an idea.
