Klitshcko-Lewis again

I know I know, that's an old fight. But I just watched it again and do you think that Klitschko would have fallen if he didn't hold Lewis at 15 seconds of the last round ?? Just a thought, and I think that Lampley was so partial and he only wanted Klitschko to beat Lewis. I think that Klitschko was really tired and hurt at the end of that round, more than people could think.
