Odell Beckham Jr. has officially said his goodbyes to the Cleveland Browns, penning a letter to the entire organization, thanking them for their support over the last three years.

Beckham also gave a special shoutout to Jarvis Landry in his letter, whom he played college football with at LSU. 

The Browns waived Beckham earlier this week, and he signed a one-year contract with the Los Angeles Rams.

Beckham joined the Browns in a 2019 trade from the New York Giants. He only appeared in 29 games for the franchise over three seasons because of injuries, catching 114 passes for 1,586 yards and seven touchdowns. 

Cleveland released the 29-year-old earlier this week after his father, Odell Beckham Sr., posted a video on Instagram showing times when quarterback Baker Mayfield didn't throw the ball to his son or missed him entirely. 

Things between Mayfield and Beckham never truly clicked, and, according to ESPN's Jake Trotter, Beckham stressed out the signal-caller, which led to chemistry issues between the two. 

Beckham addressed his decision to sign with the Rams after hitting the field with the team for the first time on Friday, saying heading to L.A. "felt right in my heart and in my soul." He added that linebacker Von Miller and cornerback Jalen Ramsey recruited him to the franchise. 

In addition to the Rams, the Green Bay Packers, New Orleans Saints, Kansas City Chiefs, New England Patriots and Seattle Seahawks were reportedly among the teams vying for Beckham's services.

The three-time Pro Bowler is reportedly set to make his Rams' debut Monday night against the San Francisco 49ers, per ESPN's Adam Schefter, which doesn't come as a surprise given the news that Robert Woods is out for the season with a torn ACL. 

Beckham initially wasn't expected to have a major impact in L.A.'s offense, but with Woods sidelined, he could become one of Matthew Stafford's top targets alongside Cooper Kupp and Van Jefferson. 

The Rams, who enter Monday night's game against the 49ers with a 7-2 record, still have the third-best Super Bowl odds despite the addition of Beckham, per DraftKings.
