Kane doesn't mind putting people over. He never puts jobbers over, only people who really have potential. Now on to Kofi.
This is all a part of the grooming process. They are trying to see who is next in line to carry the torch for RAW. Kofi is one of the more over mid carders other than CM Punk so its only right to give him a try on the big stage and see how well he works with the top tier players. Why would you put Kane in the match? Kane has been in the WWE for 11 years, he doesn't need the title to be over, and he doesn't really need a main event push. He's already been in the EC so lets have new guys in there. Kofi is young, athletic, and is a breath of fresh air. Besides it is a 6 man match, why not have Kofi in there? It is time for the WWE to really evaluate their guys and see what they can do.
They haven't created a new main eventer in a few years other than Jeff Hardy. HHH, Undertaker, HBK, Kane, JBL, Jericho, Big Show, and Batista will leave a huge void when they leave. I am assuming all of them will be gone within 5 years as they are close to 40 or older . Who will that leave? 37 year old Cena, 39 year old Edge, 36 year old Hardy.
Putting Kofi Kingston in this match is a smart move by creative because it is a potential investment in the future. It gives Kofi credibility, and will also allow him to develop his character. Everyone who I speak to who is a wrestling fan and even the IWC says that they want fresh storylines and new faces chasing for the strap. Kofi is a new face and he is actually good in the ring, why the hell would you not give him a shot....hell its 5 slots open to challenge for the belt! Kofi has a good look and most importantly he is over with the children, which means he will be in the WWE for a long time. He will go back to chasing the IC title after this, but this is the first of many title matches for this kid. We'll be seeing him in MITB I'm sure.
