You say that, but he's had some pretty high callibre matches/opponents at big PPVs since he debuted (Cena @ RR, HHH @ SSlam, Vince's representative @ WM, IC-fued with Hardy)...
If he hadn't got injured upon arrival on SD, I think he'd have received a bit of a push... He looked awesome in his last few months on Raw (seemed to me like they were trying to build him back up following some of the shittier jobbing he had to do).
Even if we only got the much anticipated program with Taker and some further confrontations with Jeff & Hunter at least he'd be getting a decent amount of match time in which to shine...
Umaga > Khali, Show, Kane and the rest of the monsters, whether ME or Midcard.... And defo Umaga > Manu!
