Parker's footwork may be troubling for Joe in all honesty. Would be an interesting fight but if it goes the distance I would favour Parker.
Parker would get handily beaten. He's totally lost his fire since losing to Joshua and has regressed both stylistically and physically. Joyce would pummel him with his jab and break him down to the point where Parker would have no idea what to do and would just resort to spamming basic one two three combinations that would have little to no effect on Joyce. I doubt we'll see a KO, but I wouldn't be surprised to see Joyce put the biggest beating we've yet seen on Parker.
What footwork? He's as basic as they come. Parker's strengths are (were) his quick hands and high workrate, plus decent chin. Aside from handspeed those are also Joyce's qualities, and he combines them with a much better jab and boxing brain.
The Chisora fight was the last straw for me. I've been a Parker fan for a few years now, but he's just been too lacklustre too often for me to hope we'll ever see anything approaching his old form again. Despite his young age I think he's physically past his prime and will only deteriorate further from here on out.
Fight of the most underrated heavy Joyce v the most overated heavy Parker honestly Joyce would literally beat on Parker for About 8 Rounds until a mercy stoppage. Joyce got dog Parker is a mental midget
Parker will lose the power and strength battle early on in this fight and be forced to fight on the back foot, holding excessively and turning it into an ugly fight. Joyce wins a decision in a very boring fight. Paint Dry Parker never fails to stink the joint out.
Foreman now probably has faster feet than Joyce. Joyce isn't about speed, he's about educated pressure. Few people cut the ring down better or make better use of their tools than Joyce. On the other hand few people make worse use of their tools than Parker. He'll definitely be the faster man in the fight, faster hands, faster feet, faster reaction speed, and it won't matter because Joyce will shut him down and impose himself on the fight while Parker will flail around cluelessly.
