the postings are interesting because you can tell by the opinion what generation a person is. THe ones who liked Hagler are in their 40s-50s and the ones who like Jones 20-30s. Just opinion. I am going to say Hagler because Marvin fought better guys.. He took a beautiful punch by Hearns which should have leveled him and came back and fought the round of history in round one. Roy did not fight the opposition of Marvin Hagler and to say he would win is just presumptuous of some. It is not that easy. And I am saying you put the Hagler who fought Hearns in with Jones and Jones has a problem. You put the Hagler who fought Leonard (Hagler was sort of inactive for 2 years since the Hearns fight) and Jones has a chance. After Hearns, Hagler fought only one time in 2 years until fighting Ray. He did not look good with Ray and I could tell this before the first bell rang. Against Hearns he looked 5 years younger than when he fought Ray. Hearns fought the better Hagler. Fact is that Jones is like alot of guys now. boxers who knockout lesser opponents with his speed yet he never fought his equals. Anda fighters equals never go down easy.
