I just noticed that this scenario has no Memphis at all! http://www.marksfiles.com/1974.html There is everything you need to know about Memphis that year, roster wise and you'll need to make Jerry Jarrett the owner.
Also, just make sure that guys don't work for both WWWF/MACW/AWA (eg, Ric Flair just moved to MACW, Lawler, Austin Idol and some other should be in Memphis, not AWA)
Edit - I have found the full and complete roster for MACW Jan 1975, the only thing I disagree about is Flair, as It has been mentioned on every other site I've been on that he was only starting to get pushed.
