You can look at it like that. I tend to look at more like what boxing, karate, kick boxing, Pride, K-1 and just about any other legitimate combat sport uses. I didn't even really think about wrestling using a ring. However, WWE uses cages and other gimmicky things as well. I doubt the promoter of the Tarver/B-Hop fight is going to come out and announce that, to settle the fight the right way, that teh ring is going to be surrounded by a 12 foot steel cage so no one can escape or interfere. A cage is what sounds gimmicky, not the ring.
