I think this may be a bridge too far ,even for Harry,though he could win a dec, he hasnt the pop to stop Willard and to get in close he risks serious damage.
if Wilard can time a right hand or left uppercut he will stop Greb Willard to Big To stronge for greb and Willard had better boxing skills than he was Givin Credit for
Greb all the way. Nobody is beating Greb without a good workrate coupled with a good fightplan however big they are. Want to put some all time great heavyweights in with Greb? It isnt a given that even they win.
Probably not. He would have a lot of trouble landing anything meaningfull on Greb and when he did it would not be something an order of magnitude beyond what Greb had previously experienced.
Greb sparred with Jack Dempsey on a few ocasions in adition to fighting heavyweight punchers such as Billy Miske and Bill Brennan. While none of these guys were Willards size they were much better finishers and composite punchers and had top end power. The fact that Willard was throwing his shots from greater range would only detract from their finishing capacity if they landed.
\ I wouldn't put Dempsey killing someone considering what he managed when pushed against someone 70 whatever pounds heavier then him in Willard.
I do not see Greb surviving Dempsey in the real thing -with one or two eyes. I do not see Greb doing much of anything with Willard besides being tossed around like a rag doll. ...Greb is great but he ain't beating Gottamn Godzilla either.
Greb would probably make Willard look like a dick and win a decision, I doubt Willard would be able to land anything substantial, but Greb would have to be careful throughout, because one hard, clean shot could spell disaster. I think the longer the fight goes on, the better chance Willard has of landing something good, or wearing Greb down. Over 15, I'll take Greb by decision.
