I think Edge seems to be the pretty solid favorite, without needing my help to overly boost him through like it was needed in the Raven victory. HOWEVER, please let it be known I'm more than willing to help convince
anyone who is willing to keep an open mind about this situation - on why voting for Edge is truly the only option there is, if you're voting fairly and logically.
I'm going to start with some basics, and we can go from there with whoever isn't convinced off the small stuff.
The only true disadvantage Edge has in this contest, is as Shocky said - he'll be constantly tied to his opponent and unable to back-peddle, run away, or keep his distance to rethink strategy. Or at least it's the only assumed "disadvantage" when clearly this gimmick works more in Edge's favor than some could assume.
How many Strap matches have you witnessed, where the heel manages to disconnect himself from the strap, then manage to find ways to cheat further? Almost anytime one has happened. Edge's gimmick and 'character' fits this role, perfectly. He's the type of guy who'd quicker rather than later find a way out of the strap and then find a way to use that against Steamboat - such as tying the strap to a corner, enabling Steamboat from moving, perhaps.
I've seen some people use the crap logic that Steamboat is stronger. How does this figure in? Under what logic is he stronger? Edge has put down power guys like the Big Show, Undertaker & Batista with his spear, all for a 3 count or longer. If Edge has that much power behind one spear, think of the damage he could do to a guy that has the body size of Chris Jericho.
Some have said Steamboat (in his day) would be considered 'the Jeff Hardy of now.'
In his day, Steamboat's high flying consisted of a cross body block and a drop kick. I'd hardly consider him "Hardy-like". Not to mention, even if this were true - none of that high flying ability is going to come in useful for a face who is attached to a heel, who won't let him get near a corner to climb it - or tap it.
I've even seen Shocky use the logic that this strap match favors the Old school Steamboat, as opposed to the new school Edge. I don't think that could be considered accurate considering Edge wasn't knowledgeable to match-types like Ladders, Tables and Chairs when he first got stuck in those gimmick matches - but he adapted quickly, learned the positives and negatives and took full advantage of everything he could. Edge is a powerful thinker and has full use of his brain to think out way before the match even takes place what he can and can't do, with a strap attached to another guy.
Finally, someone said this is a strap match and Edge won't be capable of using his signature Chairs, Ladders or Tables. Why? Strap matches have no rules - and Steamboat won't always be able to stop Edge (who'll be trying constantly) from leaving the ring and grabbing them to use at a later point in time.
Yes, Edge in doing so could set up being hung by the rope, or yanked back into the ring apron - but sooner or later, he'll get what he wants. He always does. And when that happens, he'll only become that much more dangerous.
SO, in conclusion - Edge has full advantage in this contest against the old school Legend. Steamboat was good, but Edge is better.
