1. I see where you're going with this, and it very well may be that they don't have faith in his promo skills, but what I've heard of him is Perfectly Acceptable Promo Work so far. I'm sure he knows he's going to have to step his game up if he gets the belt.
2. Agreed 100%. HHH has RAW set up where getting anyone else over is tough because he's taken the balls of everyone else on the roster.
3. I think he has improved. When he started, he was pretty much limited to the Generic Hoss Moveset, and while he's not the next Lou Thesz I think he's made great strides in terms of improving his workrate. He's been in matches with people other than Benoit where he's had to do more than be carried and he's handled himself well.
4. I think this point is what's causing the IWC heel turn on Batista. Now that it looks like he's going to get the title, all it does is start the countdown to HHH winning it back again. I could make a comparison here to HHH's idol, but I don't want Loss to have a stroke.
