Not to underrate Rigon, but I can't think of one single advantage he has over Donaire. Hand speed? boxing skills? power? Pro/Championship experience? defense? No way Jose, and there's a huge difference in the level of competition Rigon has faced, compared to what Donaire has been up against in his 12 years as a Pro.

I'm not saying Rigon isn't good, just saying that he's nowhere close to being on the same level as Donaire. The fight will be competitive for as long as Donaire wants it to be. He may feel Rigon out for a few rounds before turning up the heat, or he may decide to come right out at the opening bell and blitz him.
