Yessir.
I will say a feud with Show, whether it be with Barrett or Sheamus or anyone else, can work but it seems after years of him putting people over, they're afraid to have him do jobs to anyone. Have someone beat his ass and they become automatically the favorite in their next feud, which is what you want to do to build a strong heel. You see how they keep mentioning and trying to put over Tyler Reks

puke

knocking Show down at the Survivor Series (I think).
If Show's just going to eat Barrett's lunch like he did the Straight Edge Society, then, yeah, it's pointless.
Right now the word is Undertaker will get either Barrett, Kane, or Ezekiel Jackson at Mania. It all depends on his physical condition come April. If he can go, it'll be Barrett or the conclusion of the Kane feud. If he's still beat up, they'll go with Zeke and have an old school Taker match: start strong, get beat down, sit up, Tombstone.
