Charger Dad, you just posted something very close to what I was in the process of posting. There is nothing wrong with celebrating at the conclusion of a match, as longer as you are not being disrespectful in doing so. I can respect the wrestler who chooses to or not to display some emotion at the end. I did it as a wrestler, when winning matches that were big wins(big for me), and as a coach, I had no problem with my wrestlers celebrating in a respectful way.
It didn't work out this way in the end, but as huge of a dominant victory as Willis had, over a top level opponent, that momentum could have carried his team to win some matches that they wouldn't otherwise win, and find a way to pull off the big upset.
