As far as I know, the wife handing candy bars out to the players started at Utah during the Urban Meyer administration. I know that Shelly Meyer and the other wives of coaches (which included Whit’s and Andersen’s wives) would come by one night per week during the season and give the players candy bars in 2004. Funny how traditions like that get started and then branch out to other places.
I wouldn’t be surprised if the wife-bringing-treats deal is done at places like Missippi State and Texas — since both Dan Mullins and Charlie Strong are Urban Meyer disciples too.
