Геннадий Геннадьевич Головкин is already 30 yrs old. (His time is running out)
Carl Froch won his first title at 30+, Wladimir Klitschko hit his prime when he was in his 30s, Martinez is also a late bloomer..
That's great, But there is absolutely NO chance he will face the type of opposotion that Froch did in his short ammount of span. Klit is in a ultra thin division... & Martinez is on ....
