I assume "JLS" is John L. Smith.Price, Sumlin...did Nuss/McElwain/JLS/Petrino ever work with Price?
He and Petrino worked together on a couple of different occasions, first at Idaho (Petrino was QB/OC for Smith) and then at Arkansas (Smith was ST for Petrino). McElwain worked for Smith at Louisville (WR/ST). Nussmeier played under Petrino and Smith at Idaho but never coached with either.
As for Price's connection to all of the above, he took over at Washington State the year after Smith left there as DC. Smith then ended up just about 10 minutes away at the University of Idaho, and they coached against either other for years. But best I can tell, Price never coached with any of them.
