Davante Adams has conceded it would be "a dream" for him to reunite with Derek Carr at the NFL level.
Green Bay Packers wide receiver Adams and Las Vegas Raiders quarterback Carr were college team-mates at Fresno State from 2012 to 2013.
Adams caught 233 passes for 3,031 yards and 38 touchdowns across his two seasons with Carr, who set the school record for passing yards with 5,083 in his final season in 2013.
The Packers star has gone on to establish himself as arguably the top receiver in the NFL, making 115 receptions in 2020 for 1,374 yards and 18 touchdowns, putting him tied for the third-most receiving scores in a single season, behind Randy Moss (23 in 2007) and Jerry Rice (22 in 1987).
However, he is a free agent at the end of the 2021 season and, with no end to the stand-off between league MVP Aaron Rodgers and the Packers, Adams' future cannot be considered certain.
Asked about potentially recruiting Adams to play for the Raiders earlier this week, Carr told ABC30 in Fresno: "It would unlock some things in both of us that people haven't seen yet."
In a follow-up interview with the same channel, Adams made it clear he is not focusing on free agency but left no doubt he would be open to a reunion with Carr.
Speaking about his free agency, he said: "I'll just continue to be me and just let this thing work itself out and see what happens.
"Obviously I love Derek to death, we've got a great friendship, we still communicate really, really consistently, he's one of my best friends.
"It'd be a dream to be able to play with him but I'm a Packer now, until that where we make that decision, I guess we've just got to... we'll see what happens."
The Packers are coming off a year in which they lost in the NFC Championship Game for the second straight season, losing to the eventual Super Bowl champion Tampa Bay Buccaneers.
By contrast, the Raiders have not reached the playoffs since the 2016 season.
Carr, however, had the best campaign of his career in 2020, throwing for 4,103 yards, 27 touchdowns and nine interceptions. His tally of 36 passing plays of 25 yards or more was just one fewer than Rodgers.
