Firstly, Shogun-Hendo fifth round was 10-9, not 10-8;however I totally understand your point. I think it could have been 10-7 for Maynard as well.
Secondly, I also agree that they might not won't Davis in there with Machida just yet, because they need Davis for the future of the division and they can't risk him losing credibility again.
Lastly, I agree that Machida-Shogun 3 could garner some interest, but I disagree with you that his time is nearing it's end. Machida is only 33 and he's super talented. He's a got a few good years left imo.
