They all look pretty solid. However, I'm not sure that I see anything really "special". Sproles video from high school was "special"... Sanders video in HS was "special". With that said, I think the kid from Blinn will be a very good back, and it looks like we got some decent athletes on defense from what I can gather from some of my outside sources.
As with any/all kids that are d-1 material, I could have a coach put together a minutes worth of highlights that would make the kid look like a sure fire star... But, without seeing them for a full game, or even half a season, it's hard to tell what you really have.
Most importantly, however, is the fact that the key component is "work ethic". Some kids are "early bloomers" and will never get any better and some will overachieve in college. But, lots of kids over the years have proved that just because you were great in HS, doesn't mean that you'll be great in college.
Don't get me wrong, I think we have signed a pretty solid class given the surrounding circumstances... But, it'll be 2-3 years before we really know on most of the HS kids.
