As I stated earlier, Raven was NOT on the way out. If he was going to be on the way out, he would not have stayed for a feud with Jarrett. Every one else they've had for one offs and the like were short term and meant for short term. Hell, they gave Shamrock the title and I'm pretty sure Raven is more stable unsigned than Shamrock.
More like 3 months. At most. Just enough to not catch on. And most people I know have completely forgotten K-Kwik, and the fact that he was once K-Krush in TNA.
First off, most marks don't know AJ from you. So it doesn't matter where they put him. Secondly, Jarrett's 5 title reigns came when WCW was dying. As in when the ratings were below 3.0. Which means most people won't remember it, and didn't care.
EDIT: Jacques, if you're going to sig someone give them credit. "some guy" and "some other guy" is extremely insulting. And WMD, I will credit you with my first sig, because I like you more at the moment.
