The trick with skit shows is to get HIGHLY talented stand-up comedians like a young Chappelle, Eddie Murphy, Jamie Foxx etc., and then let their natural genius come through with some good writing.
Basically let them write up funny stuff but have other writers tailor it so that it works in a skit format.
SNL gets people that aren't elite or even semi-elite stand-up comics. They are writers who can write decent material but don't have great acting skills or stand-up delivery skills to make jokes work. The types of comics that could make this show pop get famous on YT or IG and then blow up elsewhere.
