Andre Ward is without doubt a talent. Neat boxer, tough, takes a good shot, great tactical fighter, good on the inside, fast, lovely feet and can fight and box. His stamina is very good too. Now, over 12 rds who wins this? I think Ward's speed, skills, and overall talent cause Hagler big problems. Also, he is that little bit bigger too. Plus, he is very slippy and elusive when he needs to be.
I may go with Ward on points here. I don't see anywhere where Hagler can exploit this guy to win.
