A Plan B at running back for ASU is Tyree Range. He's a former Texas Tech commit who is now hearing from ASU, UCLA, and Utah. His dad lives in Phoenix, so if ASU decided to pursue him harder I could see how that aspect may come into play.
If Trelon Smith sticks to his commitment and Eno Benjamin comes on board ASU should be done recruiting at this position even if Kalen Ballage was lost to the draft. In the event that Ballage left for the draft AND Demario Richard decided to transfer (not saying this is high probability, just throwing it out there), then it may be prudent for ASU to take a third running back and taking a junior college prospect such as Range would make sense as far s balancing out the position class wise.
All in all, ASU making initial contact here is nothing more than covering your own bases.
