Not enough data of Ibragimov but I wouldn't count him out. He could box, he could punch, he had fast hands, and was a southpaw. The guy could have had a great second career at cruiser, or even just hanging around heavy, but he didn't want to fight, and apparently had Visa troubles.
Povetkin by decision. He was a sturdy guy and more proven although Iggy would certainly keep it close. I always liked watching Ibragimov fight. He looked like Barney Rubble but had fast hands and went to the body nicely. He also wrecked Mora a lot faster than Povetkin did for whatever that's worth.
