I'd like see Holy win, it would make for an interesting story, but I don't think he will.
Ibragimov is pretty slick, he has very good footwork and movement and he's a lefty which causes problems for most. He rolls out good too.
Stylistically, Ibragimov is a bad match-up for the aging, creaking Holyfield. Ibragimov is a sharp puncher with decent handspeed, and busy hands so he's just all wrong for Evander.
If Ibragimov would really step on the gas he'd probably stop Evander, but he'll likely coast to a decision win.
