I see this has gotten buried probably because it's the middle of August (I didn't notice it until today myself), so I'll go ahead and add input.
I think you did a great job. I especially liked the Joker twist and the increased amount of Sleeper Sixes. They add fun and variety to the season. I've grown to appreciate this game as just a fun diversion we play every week. The regular season standings really don't mean a lot here (they mean way less than in CSS), so it's good to just have fun diversions and keep playing. I've grown not to overly mind playing on Thursdays when a Friday show is spoiled. I would, however, caution against that in the playoffs. I think starting the playoffs in early May to give some buffer time in case shows end up getting spoiled out is a good plan that should continue. All the playoff games should be relatively normal Friday games.
