1 ali - no need to explain 2 joe louis - fast, strong great boxing skills, intelligent 3 george foreman - a beast foreman would destroy tyson in 2 rounds 4 larry holmes - did not get the honour he deserved 5 sonny liston - wasn't just a animal but could also fight if it wasn't for ali he would be champ througout the 60ties 6 joe frazier - kept on coming no matter what only a bullet could stop him ps al people who say rocky marciano have no brains. the rock only boxed over the top opponents and lesser fighters

Rocky Marciano (49-0-0) 43 by KO Knocked out boxing legend Joe Louis in 1951 to earn an opportunity to fight for the title. Won 49 straight fights in his career. Forty-three of these were knockouts. Knocked out Jersey Joe Walcott in the 13th round to win the Heavyweight Championship. Was named “Fighter of the Year” by The Ring magazine in 1952, 1954 and 1955. Defended his title as the World Heavyweight Champion six times, five of which were knockouts. Final career match ended with a knockout of Archie Moore. Became the only boxing champion to retire undefeated and stay retired.

Lewis was a good champ, but probably not in the top ten of all time heavyweights. Here is my heavyweight list: 1) Rocky Marciano 2) Muhammad Ali 3) Joe Louis 4) Jack Dempsey 5) Jack Johnson 6) Gene Tunney 7) George Foreman 8) Jim Corbett 9) Mike Tyson 10)Joe Frazier 10a) Larry Holmes

What the hell is wrong with you people? Tyson...Tyson..? 1. Mike Tyson (No ONE would have beat Tyson at his prime- no need to explain) 2. Muhammed Ali 3. Rocky Marciano 4. Jack Dempsey 5. Joe Louis 6. Joe Frazier 7. Jack Johnson 8. Evander Holyfield 9. Larry Holmes 10.Lennox Lewis

1.Ali 2.Joe Louis or Marciano 3.Louis or marciano 4.Foreman 5.liston 49-0 people that is perfection there is nothing better then perfection which Marciano accomplished except for Ali who fought in the heavyweight division when it had its toughest competition.

1-Muhammad Ali 2-Jack Dempsey 3-Joe Louis 4-Larry Holmes 5-Jack Johnson 6-Gene Tunney 7-Jim Jeffries 8-George Foreman 9-Lennox Lewis 10-Rocky Marciano 11-Joe Frazier 12-Sonny Liston 13-Riddick Bowe 14-Evander Holyfield 15-Mike Tyson

Well I'm 4 years younger than Lennox but we trained @ the same gym for over 10 years so you guy's may not know this but in 1984 our coach Arnie Boehm was looking for new & up & coming challenges for Lennox so they went cus's gym in the catskills to with Tyson who was 17 @ the time & Lennox was 18. The first round Tyson came out trying to make everypunch a knockout & Lennox got a fat lip so Arnie says we can do this another day & they went 2 more rounds & Mike never laid another shot plus got a nice bloody nose & Cus said someday you to will meet in the pro's i just know it. So since Canada is so slow to act & cheap he went to England where he found the financial backing he refused to take in the US since Don King had heard of the 4 days they sparred & after 1 round Lennox knew what to do & that's why King paid Lennox $12 million not to fight Mike so he could fight guys he figured he could intimidate. So I know for a fact Lennox wanted Mike right after he tried to get Chicken Bowe to fight but he too knew what the outcome would be that why he tossed the WBC belt in the garbage & Tyson knew also because you don't pay $12 million not to fight so Bowe & Tyson were scared of Lennox embarrasing & throwing them around like they owed him $. As far as I'm concerned they're pussy's & should go into witness protection if they haven'nt yet. Check out CNNSI.com & look for Lewis/Tyson sparring years ago just so you know I'm biased because I know him but those were just yap flappers who tried to intimidate which obviously you can't do to everyone.

Well slothmister I'm not a real saavy computer so you check it all out. TTYL I don't know you called but whetever I'm pretty laid back, however gogle lewis/tyson sparring yesrs ago & you should definately check it out & get back to me as soon as you do!

i would say lewis

Rocky marciano was the best 49 wins from 49 fights 43 ko,to all the idiots that think ali was great he was over rated involved in fixed fights against liston and foreman.If marciano fell behind on points,he always had that killer punch to see him threw which no other heavyweight had.Ali got his ass kicked by norton 3 times but the judges gave it 2 ali twice on name alone not on effort.As for joe fraizer he was wiped out by foreman twice with ease,and lennox lewis was knocked out cold on a few occasions by crappy qaulity opponents.

Muhammed ALI, no contest.

1. Mike tyson (in his prime) 2. Muhamed ali, 3. Jack Jonhson, 5. Rocky marciano, 6. Joe Louis, 7. Lennox lewis, 8. Larry holmes, 9. Evander holyfield, 10 George foreman

Ali or Jack Dempsey without question. People don't realize how good the competition was back in Ali's day. His only problem was he stayed on a bit too long but that happens to most of them. I would put Tyson third on the list. When he was in his prime he could knock out anyone but after his prison term, he pretty much is a shot fighter. If he hadn't lost so many in recent years, you could make the argument for him being number one. Dempsey was in some ways the best "fighter" of the bunch though I am sure that he hits quite as hard as a few of the others.

I would have to go with Ali!!

sonny liston- he was better than ali

manny pacquiao

maybe,,i belive there are 4 of them but they differ in weight division and era.for me, lewis, ali, robinson and manny pacquiao
