I didnt know that FINN created a PBP slot for every player including those that dont actually exist in-game. I thought they were all there and that he just added the UNK since he didnt know who they were connected to at the time.
I still think that VC forgot because why would Crayton and David have that pop up message saying that there's been a match found in the audio database when there isnt? The reason why others like Arrington, Rolle, Booker and so many others have that message as well because it's going based on players with that name like LaVar Arrington, Marty Booker and Samari Rolle.
Think about it - if those are there, shouldnt Crayton and David be there as well especially when there's no other player to be found with the last name Crayton or David? Maybe the index number is wrong?
Type in McFadden in the CAP feature in-game and you'll get that message because Marques McFadden is in the audio file. Since Crayton and David have that message, you would think that their last names are somewhere to be found.
