Rhodes' best days were in the early 90s when he was a babyface in WCW. I have no idea what the hell happened that made him transition into the Goldust character, but I shake my head every time I see him due to the tragedy of all that potential being wasted. He could've been big, and, to make matters worse, his brother is only half the talent he was but will probably advance a hell of a lot further.
On the other hand, I have recently had the pleasure to watch some old WCCW shows, and I have been nothing but impressed with Hayes. Gordy was probably the best of them in terms of in-ring work, but Hayes just oozed charisma and was definitely not a slouch in the ring.
Ultimately, this would be an excellent match that would be an instant classic if they fought in WCW in the early 90s and they were both in their primes (I am aware this is in TNA, but, indulge me for a bit please). In a close one, I'm giving the edge to Hayes.
Pick: Hayes
