Seau is set to be posthumously enshrined in Canton in August -- and while the family will be able to make a video message to be played during the ceremony, they're pissed ... claiming they should be able to give a live speech.
And when we saw Owens over the weekend -- T.O. told TMZ Sports, he very strongly agrees with Seau's family.
"It's a time to recognize this guy and his accomplishments. If it wasn't for his family, there wouldn't be no Junior Seau. I think it's terrible if you ask me."
The Hall of Fame says they're just abiding by the H.O.F. policy. Maybe it's time to change the stupid policy.
