Joe Bugner vs. the 70's Heavyweights he didn't fight

Bugner's safety first style helped him have a long career .-6' 4" and reach could not have hurt, If your rooting for him , He pissed you off with his lack of agression. Yes he should have fought Norton for sure, the English promoter's should have broke their piggy banks and Brought Bonavena over by at least 1974, 1975 or so! Why not a Bunny Johnson, or a Jimmy Young in London?, DUANE BOBICK?? -NOT TO MENTION A BIG ONE AGAINST BIG GEORGE?
