Andrei is a big, athletic, technically skilled fighter, but you don't jump into a world title fight in your debut, thats just not realistic.

A lot of MMA guys have crossed over to boxing and had success (Belfort, Nick Diaz, Ricco Rodriguez, ect) but their wins were over nobodies. The thought of a guy jumping over and fighting a world champ (even if it is Valuev) is laughable.
