In regards to Teddy Hart, supposedly he has had a bad attitude and hence got released a couple of times from the WWE. If it is true, hopefully Teddy will wise up and make the most of a promising career.
In regards the Hart Dynasty, well, it looks like they are full-fledged faces. I think they slow-built this as if I remember correctly, they punked Jericho after he talked smack about Bret.
My concern though is them actually winning the tag titles. The WWE tends to have cold feet on this type of stuff. They turn a team, push them, then stop from completing the push.
My feeling is they could push the Hart Dynasty as THE tag team in the WWE. Have them beat Mizshow and defend the tag titles on both brands and have a lengthy title reign. they can beat up and coming teams, established teams (both current and from the past), and makeshift teams of current stars.
