It's time to let Barry Bonds into Cooperstown ... at least according to David Justice -- who tells TMZ Sports the SF Giants legend should be a Hall of Famer.
"Barry Bonds is the baddest dude of my generation," the former Atlanta Braves All-Star said this week. "The baddest dude of my generation. Bar none. Bar none."
Of course, despite being arguably the best baseball player ever ... Bonds has been essentially blackballed from the HOF after he was accused of using performance enhancing drugs during his career.
