There’s definitely a noticeable slur in Hearns. Same with Toney. Neither were the most articulate guys to begin with but there is a change in speech. A different case is Larry Holmes. He has more of a lisp than a slur, and has always had that lisp. He seems to very sharp nowadays.
Tommy was in bad neurological shape when Manny died and I guess that's over 8 years ago now. Fuck knows what stare he's in now. Dip the wick, pay for the oil, and Tommy dipped his in some sweet crude.
