Ok...just no. Cody has been put in a feud with Big Show, who is a main eventer/upper mid carder. If anything (jobbing or not), it is a step forward for Cody. Like LegendaryBazinga said, that is the problem with feuding with Big Show - the opponent looks like shit after. Well...at least when Big Show is a face. But the fact remains the same: Cody is feuding with a main eventer/upper mid carder.
Honestly, I think Cody will end up eliminating Big Show in the Rumble in some fashion. WWE has obviously been happy with the way his "Dashing" gimmick has been going as he has been getting loads of TV time and he has been (up until this current feud with Big Show) being booked very strong for a heel. I believe there was a period there for a number of months where Cody was picking up clean pinfalls basically every week on Smackdown.
So OP, don't fret...and stay dashing!
