But its not as if the brands are in danger of breaking down. No, for them to be in danger of that they'd have to actually be separate right now. Talent comes and goes on the brands as they please so its no huge thing for them to tear down that last wall and put ECW and SD! together. This actually gives a wealth of talent to ECW and the young guns on ECW to showcase their stuff on network TV
On the subject of Booker, Sharmel, and Daivari leaving.....I wish Booker all the best in what ought to be his retirement from the ring. I think he knows that WWE is the only viable place for a guy l;ike him and that going to TNA wouldn't help either party. Bookers got a ton of options here, but I hope he focuses on his school and his content at that.
Daivari, on the other hand, asked to be released. I dunno why, but I think its because hes seen how TNA handles their X-Division (jobber) talent and see that its not much different from WWE. In fact, the TNA Jobbers have deeper characters, more screen time, and far less travel to worry about. If Daivari wants to, I bet he could show up in TNA in the X-Divison and make a living there.
