This is brilliant on the part of WWE, and exemplifies what ECW should be. They're not planning to book Burchill with anything besides jobbing on Raw, so they're putting him on ECW where he can get TV time, have matches and promos, get noticed, and maybe prove himself to be worth an IC, US, or ECW title reign. With last night's match and this move, I'm fairly certain Paul won't wind up a jobber, considering he dominated Gabriel the whole match and lost via roll up, which is hardly a total job. Given also that Burchill vs Gabriel is ready made - both are British, so I'm certain WWE can figure a good angle out of that, and both have valets, one of whom can wrestle and the other of whom I hope won't embarrass herself. So you set up mixed tags, Divas matches, etc., etc., all of which can fuel the feud.
This is definitely what could and should have been done with a bunch of the recently released talent (i.e., London, Snitsky), and is a smart move from the WWE. Burchill is a top rate talent who would make an excellent ECW or IC Champion, and was a major threat to Kofi before SummerSlam, and honestly, an extended Burchill vs Kofi instead of Santino's worthless reign would have been a better direction to go. Building Burchill up with a few good months on ECW and potentially a title reign in the future is smart, and perhaps by draft time he can be put back on Raw to challenge for the IC title, or find a strong partner and run at the tag titles.
As for Katie, this is a positive for her as well. I expect she'll continue to job on Raw, unfortunately, but getting on TV with Paul, and cutting promos will help her. Potentially, this could translate to her becoming a strong heel candidate again, and maybe the breakout Diva of '09 once Beth drops to Melina (I assume she will at Rumble).
So the move looks to be a positive for the Burchills. I consider the both of them top talent in their divisions, and hopefully, this results in air time, matches, and titles for the both of them.
