Mayweather/Big Show Question

Greetings Scott,

Love the blog yada yada yada. Question for you. I was watching WrestleMania Rewind on the network last night and it featured Floyd Mayweather vs. Big Show from WM24. I had kinda fallen out of fandom around this time so it was my first time seeing it. Was quite the entertaining match, as far as a non-wrestler vs. wrestler match can be.

My question is that I noticed among Floyd's "entourage" that night was future Nexus member Michael Tarver. I had to do a double-take upon realizing it was him. At first I thought they would have him there so he could take some kind of "trained wrestler only" bump from Show, but he was only barely involved in the match. A check of Wikipedia indicated that he was barely into FCW at that point.  So how did a relatively unknown newcomer like him end up as part of Mayweather's entourage in one of the most promoted matches at the biggest event of the year?

Thanks and keep up the great work on the blog.

​Sidenote:  That was such a weird buildup to a major match, with Mayweather playing the babyface to start and Vince doing a defensive "This is a classic David and Goliath story, you heathens!" interview when confronted by investors over how silly the whole thing was.  And then they suddenly switched it to babyface Big Show and arrogant heel Mayweather, which actually somewhat worked.  And then they lied about how much money Mayweather was making for some reason.  
Anyway, I wasn't really watching at that point, but I recall hearing about Tarver being a legit bodyguard for guys like Mayweather, so maybe he got his WWE gig as a result of being involved in this one?  Worked for Test.  ​
