I'm assuming we're excluding jobbers...
Diva Division - Use the hot ones as valets. Release everyone else. Kill it with fire.
John Laurinitus - Huge mistake from the beginning. Couldn't do a promo while he was a wrestler, why is he doing them now? How hard would it have been to hire some actor to be the VP of Talent Relations? Most fans wouldn't know the difference anyways.
Undertaker - We get it. You're a legend. WrestleMania undefeated streak. Unliving man. Et cetera. I've watched Taker's progression from Brother Love apprentice to where he is now and to be quite frank, I dont care about part-time wrestlers. End the streak, sell him to TNA and be done with it.
HHH - I never liked him. From blue blood to DX to son-in-law to now. Hated him. I'll admit that I like his persona more now, as COO, I really don't care for the guy. I appreciate his importance to this convoluted conspiracy storyline, but I really don't need to see him in multiple segments week in and week out.
Matt Striker - Thankfully he's not a color commentator any more. I put Smackdown on mute because of him. I have zero interest in him.
Honourable Mention, John Morrison - Learn to talk, learn to cut a promo. If he can't do this, leave him as a mid-carder and stop wasting valuable time pushing him.
