Re: Why was Shawn Michaels/Sid Vicious at SummerSlam 95 scrapped ??
It doesn't appear that there was any heat between Sid and Shawn and Sid was always treated well by the Clique. He was always their monster heel who they could work with and he'd put them over, and they'd put him over to build heat pretty frequently. Sid and Shawn both got over on each other, and Sid's power bombing of Shawn, and subsequent feud, was instrumental in getting him over as a babyface, so in that sense, Shawn needed Sid.
Shawn and Sid even tagged with each other a few times as babyfaces and were semi-friendly before their Survivor Series match in character, both being babyfaces at the time, putting each other over in promos. Their program seemed to end well.
I think, overall, Sid wasn't a threat to the Clique and was more of an asset to them, so they liked having him around. Sure, they had to work harder to get good matches out of him, but there was usually heat.
