arreola no doubt about it,hes a better boxer and if he doesnt stop him late hell definitly outhustle peter, peter is lazy and one dimensional. Yey say what you want about arreola but he doesnt fight lazy. Although vitali beat a whupping on chris, he does have some skills to go along with his heart and power. Remember he was a national champion as a light heavy. arreola showed me alot more against vitali than peter did. Atleast arreola tried!
Against Chambers Samuel Peter looked slow and fat, Arreola is good enough to take the fight to Peter and win on points as long as the beating he took from Vitali hasn't left him with emotional scars.
If they stand in front of each other anybody can go but Arreola's a more technically sound fighter. He throws more accurate punches and is sound in other areas whereas Peter is and has always been quite crude. It would be Arreola's technical acumen that puts him in a better position to land the more telling blows and thus, earn a victory.
