Diesel was the champion and Vince wanted a big guy as a believable threat.
Yeah, Mabel winning the KOTR was a questionable move. I wonder if Mabel was a last minute win as Razor Ramon had a rib injury at the time and could have been a believable King.
The plan from what I understand was for Mabel to get one of the greatest rubs in WWF history by defeating three of their biggest stars in one night: Undertaker, Michaels, and Ramon so unfortunately, The Bad Guy would've been jobbed out in the finals again.
"Right now, I'm walking through this cemetery. Not because I'm sad. Because it inspires me. It's the most motivational place on Earth. Why is that? Because people die. When you accept the fact that your time on this Earth is limited, you'll do whatever it takes to make it count." - Bryan Bowers
