For those who believe 4-time world heavyweight champion, Evander Holyfield, has little left to fight with when he returns to the ring to face Jeremy Bates (American Airlines Center, Dallas, August 18), his trainers, Ronnie Shields and Tim Hallmark, have a message for them -- don't count Evander Holyfield out, just yet. Holyfield himself has put out the message that he's determined to become boxing's first and only five-time world heavyweight champion.  Now, after several months in the gym and Holyfield winding down training for his upcoming fight, his trainers are saying that the idea is not so farfetched.
