Retarded, it would have been better if drafter pretended to be offline and just let the lynch fail, not to mention you would have to be a real shitty player to not see what was blatently clear, which is that SA was obvious scum.
You are the last player on earth I'd be taking seriously when it comes to opinions about "shitty" mafia players lol. But under the idea that drafter was mafia bussing his team mate, it would look really good for him to lead that lynch. He constantly tried mentioning it as a reason for his own town cred. How would he have known he would be right about that? He himself doubted the read early on. In that regard your read on SA made more sense then drafters. Drafter admitted the case on SA was weak, and nothing SA did changed, but his wagon on SA only got stronger as the day phase went on.
It is of value, when you have 2 competitive lynches, one which is on a clearly scum player and one that is on a town player, then it is valuable to see who was pushing for the preferred lynch of the scum team. Most lynch wagons are kinda useless but not in these rare circumstances. I think the mafia scum wiki discusses the importance of analyzing competing wagons as well. in their strategy guide
This is why in most live mafia games, scum who bus almost constantly win. No one ever doubts the person who led the lynch on the mafia. As mafia, bussing seems to be almost unbeatable because of people like you who dis-regard it as a common thing.
