He can be charismatic but I just think he needs more of a clear heel gimmick. The reason we don't know about much of his character is because he is rarely given TV time and I think that is a shame because he is a great wrestler. I pray that he doesn't go back to the Hurricane gimmick because it was an insult to him and didn't let him show his wrestling skills. He is not a proper CW so I don't think he should be in that division so I think the US/Mid cards beckon for him.
As for Benoit, I think he is wasting his time in the WWE because they are just letting him rot and not using the talent that they have in him. He deserves to be in the main event a million times more than Batista does, and the fact that he is given very little TV time is a joke to all fans of him. He deserves to be in the main event because he has more wrestling ability in one finger than most do in the WWE. He deserves way more than he is getting and it is disgraceful that he is going nowhere in the WWE like you said, because he belongs in one place and one place only: The main event.
The fact that the fans have stuck with him when the WWE has seemingly been trying to bury him for the past two years just shows that even marks appreciate his ability and for that, his skill should be put ahead of any marketing inabilities he has. If they don't, he will be gone the first chance he gets because he has got to be upset that he is rarely acknowledged on the show and is only put in PPV's in the last second.
I think a decent feud between these two guys (Helms and Benoit) would do wonders for Helms, but again wouldn't help Benoit at all, because he needs a decent feud for the World Title because it is utter crap what they are doing to this hell of a wrestler who is a veteran who deserves much more than is given. I hope he goes to TNA where his vast talent is used because he has earned every shred of respect that he has.
