I could be wrong but what I've gathered from reading this board and others is that ASP made casting choices based on how much she liked the actor. Now, we get a little OTT with our criticism of ASP because frankly, it's funny--but can't you just picture Amy in an odd hat, calling Wayne Wilcox (the Marty actor yes?) and being the "cool friend" who totally has a tv show and wants you to come on and hang out and make money? What I'm getting at is Amy seemingly has made actor choices not based on what's good for the plot (see the Revival and the SH musical) but because she has her pet folks who she wants to work with. It's sort of cute and nice in a way, but damn, she destroyed Marty's character.
