Stars who had potential but never made it or were never used right

[Providence Peep]

Hi, everybody. Just joined here and thought I'd start my first post.
The title says it all. Which stars do you think had great amounts of potential but were either never used right and or never made it big?

My list:

Mr. Kennedy: People were expecting him to win multiple World Titles. He had it all, charisma, mic skills, ring skills, etc. but in the end it didn't work out for him in the E.

Sean O’Haire: He had tons of potential. He was a big, charismatic, athletic, a powerhouse. In fact he reminds me of a tall CM Punk. But the WWE didn’t even give him a shot. I never understood that one.

Mark Jindrak: Another big, athletic powerhouse with a ton of potential.

The Brian Kendrick: The WWE showed us that they were interested in him while he was on Smackdown. He had everything going for him, especially since at that time (and since then) size was playing pretty much no importance on who could be a world champion. He had a good heel persona, and good in-ring skills. Yet they gave him nothing after a while because he used weed.
