I like Kozlov. Heck, at least he's somewhat entertaining for a big man, which is more than I can say for any big man in WWE whose name isn't Paul Wight. The headbutt finisher does suck though.
As for who ends the streak, I'd like to see MVP do the big face turn or have him feud with Mr. Kennedy when he returns from *yet another* injury. The feud with Umaga, although it was never given the five-star treatment, was great face build for Kennedy and this could be the big one that puts him over. Sure, Kozlov isn't particularly over, but I'd like to see Kennedy vs. Vladimir Kozlov.
