Not mad at you but here's my take. WWE is in trouble, (if reports are true) financially. They've cut performers with more to come possibly. Cena is their only real money maker and his influence is hard to figure. It's a split reaction from live audiences while he moves merchandise and headlines ppvs, his company with him as the face of it, is cutting performers. He can't take enough time off to heal from injuries and they are lost when he's not there.
Orton, Sheamus, HHH are good but let's face it, they aren't money like Cena is. Bryan is injured, his future is uncertain. Punk has left. Reigns, Ambrose, Rollins are good but we don't know if they will carry WWE to the next level, Cesaro is good but not much of a talker and Bray is really good as a character but like the others will he be a money maker this company sorely need ? Miz and Ziggler for some reason have been delayed a push as main event level for some reason which I can't comprehend.
Now Angle isn't great for the box office on his own but his presence in the main event helps greatly. His experience in the ring can help teach other performers how to put together a more entertaining match for the fans which could lead to more money.
Punk is a non issue to me. He left and said he didn't like part time performers. Fine there are reasons not to like them, but he was champ for 400+ days and yet the ratings and revenue during that time with a roster full of those full time performers was abysmal. His biggest money making matches were against part timers the Rock and Taker. The locker room can be angry about part timers coming in but they are part of a company that can't make money off their full time contribution and releasing them to make money. If they quit, where would they go that offers the same amount of job security, pay and notoriety ? TNA may be off the air soon, ROH is struggling, the indys are unreliable. I get the irony here that the company can't pay these guys and has to let some go but can afford to pay for some of the signings like possibly Angle and the guy from Japan but WWE has to do something to stem the tide of money it's losing and bringing in Angle will help in the short and long run. If the company is losing money it must look at the on air, in the arena product and fans have been dissatisfied for a long time in that regard. Angle in the ring produces a better product in the arena, on tv on ppvs , that leads to better results money wise, it has to be done.
