I am in L.A. for the National PAL, and the walls of my childhood room are covered with Tyson articles from the Los Angeles Times, so I am able to reference at a glance much of what was said back then. It supports what I have been saying. Feb 23, 1990:
Said Matt Baranski: "People don't realize it, but Mike has taken a lot of shots in the gym...I've heard he looked realy bad in sparring [training for Douglas]. I heard Trevor Berbick gave him a hard time in sparring...Trevor Berbick is as slow as molasses. He can't get out of his own way. If [Tyson] was having problems with Berbick over there, then Mike is really gone."
Tyson trained at Johnny Tocco's gym two weeks before leaving for Japan. Tyson had often trained at that gym. Tocco said, "It was the worst I"ve seen him. He was not in condition when he left here. He was having a rough time with Greg Page, he could do nothing with Trevor Berbick and even Oliver McCall gave him a bad time one day. Page hadn't looked that good against anyone in years.....It's not the same Tyson."
Said Bruce Trampler, the the famed and well respected Top Rank matchmaker: "Berbick called me from Tokyo. He told me everyone was beating [Tyson] up in the gym, even him. He said, 'This guy is in terrible shape - he's got no reflexes, no zip, no life.'"
Said Tyson: "I never took the fight seriously." Tyson said that he had fallen into sloppy training habits because of all his easy victories. He said he lost 25 pounds in 5 weeks of training in Japan [which translates to 5 pounds per week, which anyone knows is unsafe and draining to the human body, leaving him looking good, but destroyed inside. He would have been better off coming into the fight fat but without having ruined his constitution.]
