I think you might find that those folks became better writers/artists in spite of Shooter.Shooter wrote the second Superman/Spiderman team-up (which a lot of people at the time considered the best Superman story in years). Further, many people he trained/cultivated at Marvel ended up going over to DC and rebooting the character (Byrne, Stern, Louise Simonson, just to name a few) in the 80s-90s. All of that would tend to show he probably would have handled very well indeed.![]()
Byrne under Shooter: classic runs on X-men and FF
Stern under Shooter: classic runs on Spiderman and Avengers
Simonson under Shooter: classic runs on Power Pack and X-factor.
Let's not forget that under Shooter he took a collection of dated characters and built an entire universe around them in the form of VALIANT and added intriguing new characters to that mix.
