From what I gather they hardly ever talk to anyone about things and they don't really participate in camps, or at least not much, so nobody really seems to have much info on them. That being said, I think there are some recruiting writers from other team's sites that tend to think of them as almost definitely going to UT.
Should you care? Probably. Neither is going to be their big brother but they both would be solid recruits, no matter what their last name was. Plus, dey fast.
Only real problem I could for see is to what position they will project, especially the one (Elliott, I think?) who talks about playing WR at the next level.
