They paired him up with Vickie because the dynamic was proven and it made sense for his "ultimate opportunist" character. That Vickie pairing hasn't quite worked out the same for anybody else - there's a reason for that. And she took her character to a new level with Edge, as well.
This is something that's definitely worth noting. The fact that Edge is a low-key scumbag (I personally like the guy b/c I missed a few years so I'm indifferent on that Hardy/Lita situation) is the reason why I can be more captivated & drawn in by THIS...

...than I can by THIS....

...even though I'm 100% behind Dolph's work & the idea of him becoming a champion. Something just rubs me as awkward (at times) in his promo work. I want him to succeed and get to the top SO bad but man....I don't know..
You guys are right. That Matt/Lita thing might have been one of the best things that happened to Adam.

to coke boy and that's like "you getting money? I can't get none with ya than fukk ya" (What Up Gangstah?)

) until pairing up with Jericho later in the year. 2003 was a year he took off, interacting with Rock, Austin, Jericho, etc... then in '04 with Trish and the Jericho feud. Then, he got injured and didn't do much for the rest of that year, then you have the Cena shyt in '05. So yeah, any time before '03, Christian as a singles star wasn't quite cuttin' it.
