Think of this from a "growing talent" POV, they need stars and vets to prop up these young dudes, help them gain experience. In 2-3 years, you want some of these green indy dudes to have learned a shyt ton from the Punks, Danielsons, etc. Even the Mark Henrys and Big Shows backstage. Even their best guys like Kenny, naturals like MJF, and most over guys like Paige can all benefit from learning and working matches with these "budget busters".
And even if it you look at it from the POV of they want these dudes to just be the stars, and not try to elevate anyone with them.. Danielson at least looks good still, and in the ring already the best or top 3 talent on the roster. I know I'm more interested in the program immediately when I see he gonna have a match on either of their shows.. There is really no negative to that signing.
