Maybe if Sheamus does turn heel and holds the US belt for a while, it will gain some importance. I like Ambrose a lot but I kept forgetting he held the belt. He had it for a year and can't remember any memorable feud he had over it.
I was watchin that 1988 clash of champions and I forgot all about the US tag team titles, and back in the day the only reason anyone cared about them was because the Midnight Express always had them, and they could get heat anywhere they went. Sheamus needs a heel turn anyway.
