Amazing observation there buddy. You just come to that conclusion, or have you been keeping it a secret for all this time?
2. They're not SIGNED to any brand. Since it's all staged, Vince McMahon assigns them to a show, and that's the show they're on.
Captain Obvious strikes again. However, you do realize that when you are
assigned to RAW then you (mostly) only travel with the RAW talent, work the RAW shows, and take part in RAW storylines, and the same holds true for SD. Therefore, when you are traded from one show to the other, while yes, you do still work for the same company, you are now working with an entirely different set of writers, crew, performers...pretty much the only thing that stays the same is the name on the paycheck.
3. Ken Kennedy was injured all the time? What about Roidtista? He gets injured like twice a month. You wanna talk about injury prone, talk about Roidtista. I really believe the only reason he still has a job is because he's friends with Triple H. I also believe he's the only one who gets away with doing steroids.
This has absolutely nothing to do with the topic of the thread. Batista gets injured a lot. Ok, fine. Did he get traded to RAW then released shortly thereafter? No? Then he's irrelevant to the discussion. Better question. Did he have to give up a main event push to miss months due to an injury, make a huge reappearance on RAW months later and call out the champion that night, only to get injured again in his first match back, that very same night? And almost cause an injury to the champion in the process? No. Kennedy did though. That's why he's on TNA now...
4. Most of those guys who got released got released because Vince McMahon didn't have anything for them to do storyline-wise.
Wow...finally, your fourth and final point actually has something to do with the topic of the thread. I'm impressed. Most bad posters aren't capable of that much.
Now..on to my thoughts on this topic.
Its an interesting idea on first inspection, to think that being drafted to RAW is a death sentence on your career. However, when you look at it from a wider angle, maybe not so much. RAW has always been the flagship show, and therefore generally has the deepest talent pool. There is usually quite a bit of talent on the RAW roster that gets under-utilized, or ignored completely. Once a year, these guys get an opportunity to get a fresh start by being drafted to SD or ECW.
In return, several performers go to RAW. Usually one or two big names, such as Cena, HHH when he went back, Big Show, guys that you know are going to immediately be in the main event scene or at the very least the upper mid-card. Then you have guys like Shelton Benjamin, Miz, Carlito, guys who were in the mid-card on whichever show they were on who have a shot to prove themselves on the flagship show. Sometimes it works out, as it did for Miz. Sometimes they start strong, such as Shelton getting a clean win over HHH in his first RAW match, but then taper off due to a lack of skill, personality, or a combination thereof. In Shelton's case, he had all of the skill in the world, but no charisma to make it work. But his skill kept him working with the company and eventually landed him on ECW.
Then you have guys who are moved primarily, I believe, to make room for the new talent going to the other shows before being released. Look at the names mentioned in the OP. Chuck Palumbo, Kenzo Suzuki, Hiroko, Danny Basham, and Mark Jindrak. More than likely every one of these guys had their pink slips filled out already, and were moved to RAW first for the sole purpose of filling out the draft, as opposed to being fired from the show they were already on.
Think about it: you know that you have four guys you need to get rid of, you also know that the draft is coming up in a couple of weeks. There are several guys you want to move to SD and ECW, but only one or two you really want to bring in to RAW. Do you fire these four guys now, then move two or three you didn't really want to move over to RAW so the draft doesn't seem too lopsided, or move those four guys over in the draft and wait a few weeks to let them go?
And then you have the guys like Kennedy, who are moved to RAW, get the huge push, but can't live up to it for one reason or another. In Kennedy's case, it was due to carelessness in the ring.
Take a look at some of the most recent moves to RAW. Miz moved over and started his "feud" with Cena. He worked his ass off and is now one of the most entertaining guys on RAW. Swagger moved over at the same time, put on a strong showing against Cena in a losing effort, but whether it be due to poor booking or just an inability to connect with the fans, he's faltered since then.
Kofi made the move and started a slow run. While his push has slowed recently, his success isn't exactly short term. Since he made the move to RAW he has held the Tag Titles, the IC Title, and the US Title, and now has solidified himself as a top mid-card talent that is not completely out of place in the ME scene. MVP, on the other hand, tried to jump straight into the ME scene, calling out Randy Orton on his first night on RAW, only to have the feud go nowhere and watch his push shrink week after week.
My point with all of this is simple. For every Chuck Palumbo, Mark Jindrak, or Danny Basham, you have a Kofi Kingston, Miz, or Sheamus. Being moved to RAW isn't necessarily a death knell, its more or less one shot to either sink-or-swim. And we've seen over the years that some guys swim, some guys sink like a rock, and the majority just tread water.
