The Collinsworth & Aytes situations make it very difficult. Logically, you would RS one of the following:

Andres
Nixon
Toolson
Chatman
Nielson
Bartley
Worthington

But why would you RS Andres or Nixon when they specifically didn't go directly on missions so they could contribute right away? With Collinsworth's health in question, you can't RS Chatman you could be left without a PG. Toolson is probably your #1 offensive wing player off the bench (no offense to Halford, Fischer, or Winder). Neilson will have been back for a while by the time the season rolls around and has a better offensive game than any of the other bigs returning next season.

That would leave the awkward situation of RS'ing either Bartley or Worthington before their Soph year. Both of these guys bring a defensive presence that BYU needs after the abysmal defense we played last season. Not to mention, RS'ing either of these guys ties up a scholarship for another year with a middle of the road talent.
