Considering Grebs wins over some great LH/Ws.. and the HOF'er Tunney, how does he fair against lil' Tommy??? Tommy was nothing more than a LH/W afterall... especially in the modern game.
If i've got Burns right, his strength lay in his great punching power and his ability to surprise opponents and land with that power. I suspect Greb is the right man for that particular job. Wide decision for Greb.
