Source If Utah is going to take the next step, they need Fesenko to come in and provide some "Birdman" like minutes. Fes has a powerful body like an Andrew Bynum or even Greg Oden, but he came in extremely raw and lazy. If he can mature in this next year or two, this could be a Mark Eaton type guy...if not he's Ostertag v2.0
Koufos probably does but Fesenko is the better of the two as a defensive presence. Fes definitely has the physical attributes out of the two if you ask me, but his work ethic is much lesser.
