WWE have been thinking about bringing in Teddy Hart, although, they are wary of him. Harry Smith has a good reputation, whereas Teddy Hart doesn't have a good one. If he did, he probably would have been in the company a few years ago because WWE likes the idea of having the grandson of Stu Hart and the nephew of Bret & Owen Hart employed.
I've heard about the problems with Teddy, including his ego problems. I think WWE is worried that he would be another Randy Orton in that he's good in the ring but an a**hole in the back.
