This Is Really A Basketball Card Set?

I was recently cruising Ebay looking for some cardboard of one of my favorite former NC State players T.J. Warren.  I am always looking for cards featuring him in a Wolfpack uni, but I have branched out at times for some of his Phoenix Suns cards.  Since I really don't know a lot about basketball cards I mainly just set a price limit for myself and then go hunting based on the appearance of the card.  It sounds superficial, but it's truly how I collect basketball cards.

It just so happens that the day I went hunting for T.J. Warren cards, I ran into an auction that was about to end.  The card looked sweet, so I quickly placed my bid.  I didn't really pay attention to most of the details outside of the fact that the card was dirt cheap, white with two memorabilia pieces, and it was autographed.

A few days later it showed up in the mail.  I took it out of its envelope and looked at the white and grey.  The cool looking piece of basketball relic.  Then I read the name on the top "Excaliber".  Seriously?  I thought for a minute about some sort of connection between a sword and basketball, or King Arthur and basketball?  I guess King Arthur had a court and basketball is played on a court.

I'm going with the court thing.  Royal Court.

Basketball Court. 

This is surely what some designer at Panini was thinking?  Right?  Although, when I saw the Excalibur heading on the card I couldn't help, but think that perhaps someone was really sneaking in some Monty Python at work.  Maybe this could fit too, but I am at a loss for a basketball connection....
