well, if i had it my way KU would have a D-1 wrestling program, but i am not in charge.
as for all wrestlers playing football, if they are not playing football then they should be running cross country or playing soccer. i have seen plenty of 'one sport wonders' who would have been a contributor to another sport but for one reason or another did not participate. the first week of practice is an essential part of the season, it allows you to review basic techniques and sets the tone for the rest of season.
