Just been poking around looking at some of the staffs Littrell has been a part of and seeing who he has coached with. Did you know he and Jon Fabris were together at Indiana? Or that Littrell was hired by Mike Stoops at Arizona to fill the very position (RB/TE) vacated by Dana Dimel when he returned to K-State with Snyder in 2009?
Anyway, this is not at all comprehensive but there are some interesting names. Somewhat surprisingly the search didn't turn up a lot of WR guys (though many of the coaches listed at other positions have spent time at WR). The North Texas board seems to consider AHC/WR Mainord a better candidate than Harrell to succeed Littrell as head coach there, so maybe he's one who stays behind. If there is going to be an opening I wouldn't mind seeing Colin Klein retained as one of our WR coaches...it would allow for some continuity with our local recruiting as we head into a key class.
