It's sort of hard to compare them, look wise i'll give you 100% of it. But alot of Billy gunns persona was not hindered by the product he was on (non-pg). Ziggler seems like a watered down billy gun because heels are so limited in how they can antagonize people. I see where the comparisons come from but.
I honestly don't understand why Dolph Ziggler and Billy Gunn are linked by some. They're both blonde and Ziggler uses one of Gunn's moves. Is that really a strong connection?
By that logic, The Miz is a Jake Roberts ripoff. They're both brunette, and Miz uses Roberts' DDT on occasion. That makes EVERY BIT as much sense as linking Ziggler and Gunn.
