Yeah, I don't see how a sneak attack would automatically make someone look weak. The whole point of a sneak attack is that the guy being jumped doesn't see it coming, thus the attacker automatically has the advantage. It also depends on how vicious the attack gets. If it's something like Austin immediately whacking Pillman in the leg with a cane and then wrapping a steel chair around his ankle and stomping on it for good measure, then yeah, no one looks weak in that scenario. If it was a smaller guy attacking a much bigger guy and doing so without the aid of weapons (like Christian attacking Batista, for example), then that would make Batista look like a pussy but Ambrose and Rollins are pretty much the same size more or less, plus Ambrose is supposed to have a mean streak.
