Alot depends on how "current product based" this is.
I mean Savage for example... he's a great in my book, but his relationship with WWE and Vince in particular is strained to say the least.
And its the age old questions that always come up:
Is it who's done the most for wrestling?
Is it the person who has spear-headed the greatest period in wrestling? i.e Austin/Goldberg
Some would say as great and as much as Hogan was... Austin's contribution to WWE was the greatest of all time.
Does it matter how long you were in the industry? Or is it how great you were while you were in the business.... Coz while the Rock was around he was as entertaining as anyone IMO
So many greats.... is it possible that no1 could be someone who never was a world champion?
etc etc etc
So many that could lay claim a top 10 place but IMO only 4 or 5 can lay claim to No1:
Flair, Hogan, Austin, Taker & Bret.... i'd put money the winner would be out of those 5.
But until the criteria is set, its hard to decided
