I agree with you about the scholly being better utilized elsewhere (i.e. Starks and lineman). My point was, that if you had NOT seen d'Onta highlights, that you should go watch. I don't believe d'Onta NEEDS to "ride Armanti's coat-tails" as you stated; particularly when Armanti is wearing a "sport jacket".

I believe d'Onta will be a very productive RB in college and will have D1 offers by the time his SR is over.
IMO, d'Onta is on par with Perine, so if the coaches REALLY wanted Armanti that bad, they would have taken his brother by now as well. Despite the slight body difference, d'Onta and Samaje are very similar backs.
I mentioned on another site that this may go beyond football. Perhaps Armanti is pulling really hard simply just to get d'Onta into a better, higher-education institution for career purposes. NFL prospects are always slim, so maybe they're just trying to get as good an education as possible. Just conjecture on my part though.
