Just because it says WWE is signing "Indy Talents" doesn't mean that it will be the top indy guys that most here overrate. Technically, a wrestler who has a match as his local national guard armory is an Indy Talent. Now if the guy or gal has 0 experiance then I guess they aren't an "Indy Talent".
As far as roster cuts go I'm shocked to but, I wonder how much holding on to some of the guys and girls especially ones like Camacho who has potential and could easily be repackaged (think Skip Shefffeld to Ryback) has to do with not wanting them in TNA?
Half of the people signed will never make the full-time roster in WWE also. The point is to get them in the system and try to develop them into a full-time roster member. If a particurlar worker doesn't work out they'll get released and one to the next one.
I'm not too sure what you're talking about. They aren't signing "indie talents" as some kind of abstract notion, or some kind of future promise, we know each and every person they sign, and they've been regularly signing indie guys since 2011. Jon Moxley, Tyler Black, Claudio Castagnoli, Chris Hero, El Generico, PAC, Brodie Lee, Sami Callihan, Sara Del Rey, these are all well known top indie wrestlers, and before them Daniel Bryan, CM Punk, etc, too.
There have only been a few little known indie wrestler signings, like Sterling James Keenan or Davina Rose. The whole point of these indie signings is they are signing the standouts, who tend to be th top of their indie promotions. If they are experienced standouts, there will be very little development needed, they already know their strengths.
