Fedor hasn't proved anything in MMA in over 3 years, he may win (90% of MMA fans think he will) and Sylvia would be a great start for him.
Don't discount Timmy, while he is one of the least liked HW's in MMA he is no chump and the only way I see him winning is through decision, albeit an unlikely outcome, I will be part of the 10% (at best).
