Quite a few unexpected turns in that video. I'll say that much.
Everything was completely plausible aside from the glossing over of Shaq's career. Did he blow out his knees in Orlando ? I'd be interested to see what factors were involved in prime Shaq somehow failing to completely abuse the league for a handful of years. Here on Earth-2, he proved to be an unstoppable wrecking ball freak of nature that carried the lakers to three titles with Kobe as his sidekick.
Everything else in the video makes total sense.
