I've got three different pairs of black shorts, from two different manufacturers, made of three different kinds of fabric. All have been acceptable at camps ranging from local HS camps to bigger camps given by D1 guys.
While I have suspected that my choice of shorts is the reason I'm not working D1 yet, the evaluators keep giving me this line about not enough experience/ability/knowledge/presence/fitness/etc. I wish they'd just own up to it and tell me it's the shorts!
