The 31-year-old centre-back has made more than 70 league appearances since arriving from Manchester City in 2007, helping the south coast club achieve FA Cup glory a year later.
However, the Frenchman has just 12 month's remaining on his current contract, leading to speculation linking him with a move away from Fratton Park.
Aston Villa, Liverpool and Sunderland have all been tipped to sign the stopper this summer.
And after Black Cats' boss Bruce admitted that he would like to do a deal for the defender should the opportunity arise, ex-Arsenal captain Adams says Distin would prove to be a solid acquisition for at least another two years in the Premier League.
"If I was Steve Bruce, I would sign him tomorrow," he said in the Sunderland Echo.
"Sylvain might be in his 30s now, but he's still lightning fast and I reckon he's still got another two or three years left in him at the highest level.
"He's certainly someone who is comfortably a top-half of the table player and if Sunderland are looking to bring in a player who can improve them, then he fits the bill."
