At this point in time, Vitali wins on points. Haye will fight a "please don't KO me" style that makes this go the distance. I'd say the card would be more lopsided then the Wlad fight becasue Vitali actually knows how to throw counters, but Haye didn't do much of anything to win rounds in the Wlad fight either. Vitali wins at least 11 rounds.
If Haye fixes his stamina problems he has a much better chance. He should go for infighting. A lot of body shots (liver shots too) and hanging on Vitalis and putting his whole weight on Vitali to kill Vitali's stamina. Then go for a late stoppage. I wonder how that would end.
Haye does against this version of Vitali (unless it goes the distance and he is robbed) Hence the duckage from Boente and Vit
Vitali takes this fight every day. Haye does not have the BALLS, the STAMINA, the CHIN to take it to VITALI like he would need to in order to win!
If Haye gets bold and wants to engage in an attempt to nail Vitali, Haye gets caught and KOed, or TKOed. If Haye is hesitant to engage and moves away the who fight, Vitali on points.
At this stage, vitali cannot take Hayes punches He will be slashed to ribbons, torn to shreds and left on the canvas a quivering wreck his career in tatters, his legacy moot Boente knows
Vitali is 40+ and looking worse each fight. Haye is still in his prime. Barring name value I see no reason to favour vitali. I pick haye by late stoppage.
