Martellus Bennett, Devin McCourty, LeGarrette Blount and the rest of the Patriots boycotting their White House visit over Donald Trump are making a silly mistake ... so says Tony Gonzalez.
With at least 6 members of the Super Bowl squad saying they refuse to meet President Trump -- we asked the future Hall of Famer what he would do in the same situation.
"If they don't wanna go, that's their right," Tony said ... "For me, I think that's silly."
"If you've got a problem, go there and meet him! Say something! That's your opportunity to get your voice out there, to get heard."
"Tell him what's on your mind," he added ... "Maybe he'll listen."
