Cactus Jack in WCW

From what we saw Mick Foley do in the WWE, was there more WCW could have done with him?

Other than the horrible Lost in Cleveland skits in 1993, I don't know what else he could have done.  It seemed that storyline wise and based on his character, there just wasn't room for him to become WCW Champion or even
US Champion.  

No way.  He easily, EASILY, could have beaten Vader in 93 and had a run with the title for a bit as a underdog.  It was exactly the formula that WWF ran with in 98 and it worked great.  It was such a perfectly set up storyline and WCW just flushed it completely.
