You could probably make a top 50 of guys that WWE has buried.
Christian Cage was a fan favorite in 05 and he left the company and had a great run in TNA.
Samoa Joe was great in a rivalry with Brock Lesnar, this is when Roman was boring as hell. What did they do with Joe? Sent him to NXT... Nowadays he's doing who knows what in AEW.
Off the 00s alone you could make several top 10s when wcw/ecw went out of business and vince thought he could bury all the talent to make wwe talent look strong. It eventually was one of the main reasons why wwe became a shyt show for most of late 00s and majority of 2010s
