It's what the Briton does correctly that interests Grant as he gets ready to try to take away Lewis's heavyweight titles next week.
Surprisingly, Grant said in a conference call Thursday from his New Bern, North Carolina, training camp that he hasn't watched any tapes of Lewis bloopers as the two men get ready to fight April 29 in Madison Square Garden for Lewis's World Boxing Council and International Boxing Federation titles.
And there have been a few fights and rounds that would not make a Lewis highlight reel.
Lewis was knocked out by journeyman Oliver McCall in 1994 in the second round. More recently Shannon Briggs stunned the big Briton in the first round of their 1998 fight, but Briggs punched himself out, got sloppy and Lewis went on to stop him. And there have other rounds and other fights when Lewis looked less than a world beater.
But the 27-year-old Grant isn't looking to build his confidence by banking on Lewis making the same mistakes.
In the 10 weeks of training for the biggest fight of his life, Grant said, "I didn't look for his mistakes. I looked for how he was winning his fights. I was looking for his strengths to see what it is and, you know, how to get out of it."
He said he has learned that Lewis, 34, is strong and a good athlete and he likes his right hand. The 6-6 (1.98 m) Lewis figures to weigh in at roughly the same 250 pounds (113 kg) as the 6-7 (2.01 m) Grant.
But when pressed for specifics of what Lewis does best, Grant (31-0) was vague, maybe by design.
"His strengths, his strengths, his strengths," Grant thought out loud, "Uh, his style, he carries himself back in the lean position. He uses his athletic ability."
Grant was quick to pay Lewis respect, saying, "I don't think I can take anything from the guy. I can stop him from using it. I can stop him from executing."
Grant said his plan is to "pressure the guy and take him the full 12 rounds. When you put pressure on a guy sometimes he pretty much doesn't want any part of that. You have to impose your will on that person. I will develop a pace he's not accustomed to," Grant said, adding that the pressure is designed to limit Lewis's chances to think.
Lewis (35-1-1) has been criticized, particularly by his trainer, Emanuel Steward, for thinking too much in the ring, for taking his love of chess and its contemplation into the ring.
Grant said he is completely over his last fight in November when Andrew Golota knocked him down twice in the first round and dominated him for most of the fight before Grant stopped him.
"I was shaken a little bit and was laughing. I couldn't believe I was knocked down."
Grant finally caught Golota in the 10th round, knocking him down. Golota quickly got up and did not appear to be hurt seriously. But he quit.
From that fight Grant said he learned not to take people for granted.
"I got too cocky at some point going into the fight," he said. "I learned patience gives you experience ... I learned about life."
Steward said earlier this week he didn't see anything other than the right hand that was particularly impressive from Grant in the Golota fight. "It really didn't prove much," Steward said, because "when things get tough Golota doesn't want to fight."
Grant is not worried about working on his power against Lewis.
It's already there.
GRANT PROMISES A FAST START
By David Field, PA Sport Boxing Correspondent
Lennox Lewis must be ready to fight in the fast lane in next week's world heavyweight title defence against Michael Grant at Madison Square Garden.
The 6ft 7in Grant has promised to hustle Lewis with speed and pressure, though the former basketball player and baseball pitcher is not the quickest of starters himself.
Some critics say the tallest of Lewis's challengers needs to get hit first before he can begin imposing his own influence on a fight.
It happened when Grant had to climb off the floor twice in the opening round of his last bout against Andrew Golota before winning in the 10th.
"I'll pretty much pressure the guy, take him the 12 rounds and what happens when you add that amount of pressure on a person - either they don't want to be a part of it, or they gamble and go with it and end up getting hurt, either by a knockout or TKO," insisted Grant, 28.
"You have to apply your will, you've got to keep going, keep pressing, which is going to develop a pace he's not accustomed to - or he may have been accustomed to before, but things have slowed up for him. Things haven't been that way for him for a while.
"You've got to jump on the individual and not let him think. That's what's going happen, not to let him think
"But to beat Lennox is going to take everything that makes a champion, that's character, you've got to outlive the individual, that's what I've been focused on.
"This is the fight I've waited for to show my talents. I'll pretty much go out and make a big impact, it's definitely going be a great fight, and Michael Grant is going prove he is the truth. I'm more concerned with the fight than the title belts.
"I've got to be busy, more moving hands, getting out of there and impose my will on that person. The division needs a fight like this, the public pay their money to bust our backs and we go out there to do our best.
"Everything is on the line for Michael Grant, everything on the line for Lennox Lewis. Lennox has experienced a lot, I've had to lay down everything to get to this spot".
Grant's trainer Don Turner has literally been making his man work harder to rid himself of the bad habit of dropping his hands, thus making him prone to Lewis's numbing right hand.
If Grant has let his guard drift low, Turner has been stopping the round in the sparring, putting the stopwatch back to three minutes and making the big man start again.
Grant added: "When I drop the hands you've got to start the round again. It makes you concentrate on keeping the hands up. It's working in my favour. Lewis's right hand is one of his biggest strengths".
