On Thursday, the Los Angeles Rams made the latest in a series of win-now moves for the 2021 season. This one, though, didn't involve a trade, as the Rams signed free-agent wide receiver Odell Beckham Jr.

In L.A., Beckham joins a receiving corps that already includes Cooper Kupp and Robert Woods—two of this season's top 25 receivers in yardage, with Kupp leading the NFL. This begs the question: does adding Beckham give the Rams the league's best WR trio?

We're here to answer that very question.

Last month, we examined the NFL's best WR duos heading into Week 7, but this is a little different. There's a difference between having two elite pass-catchers and having three wideouts who can operate as an elite unit.

Here, we'll rank the top three WR trios heading into Week 10. We're looking at wide receivers only, so elite tight ends like Travis Kelce and Mark Andrews won't qualify.

Rankings are based primarily on 2021 performance, though past production, player health and current-season upside were considered.

7. Tyreek Hill, Mecole Hardman and Byron Pringle, Kansas City Chiefs

Combined 2021 Receiving Numbers: 124 receptions, 1,399 yards and 9 touchdowns

The Kansas City Chiefs' trio of Tyreek Hill, Mecole Hardman and Byron Pringle has been impressive as a group, albeit a top-heavy one.

Hill has been responsible for 55 percent of this trio's yards and two-thirds of its touchdowns. Hardman and Pringle have each topped the 250-yard mark and have found the end zone. Kelce is a big part of the Chiefs offense, but Kansas City ranks sixth in passing yards due in no small part to these three.

Are those numbers helped by having a dynamic quarterback like Patrick Mahomes under center? Sure, but they would be dangerous regardless of the quarterback.

Hill and Hardman are both proven deep threats capable of stretching the field, while Pringle has emerged as a similar player. He leads the team with a 14.2 yards-per-reception average and has provided a passer rating of 131.2 when targeted.

This group could explode over the second half of the season if Mahomes (10 interceptions, 92.5 rating) stops making uncharacteristic mistakes.

6. Justin Jefferson, Adam Thielen and K.J. Osborn, Minnesota Vikings

Combined 2021 Receiving Numbers: 120 receptions, 1,450 yards and 13 touchdowns

The Minnesota Vikings also possess a relatively top-heavy trio, though they happen to have two standout receivers at the top.

The duo of Justin Jefferson and Adam Thielen ranked No. 2 on our list of WR duos for good reason. They've formed a spectacular pair and have accumulated 91 receptions, 1,109 yards and 11 touchdowns.

Third receiver K.J. Osborn is only coming into his own this season—he didn't have a catch before 2021—and having that reliable third option has been huge.

"[Jefferson and Thielen] draw plenty of attention, though, with safeties often rolling toward them to try to take away Minnesota's best weapons. That's why a productive and reliable third downfield option is so important," Dave Campbell of the Associated Press wrote.

While Osborn may not be as prolific as some No. 3 receivers on this list, he's done a fine job of complementing two Pro Bowl-caliber talents.
