I'll give ya Evans would have maybe gone elsewhere but nobody will convince me that if we told cotton he could be a perferred walk on with his bro his dad as the coach and his family in lincoln that he would have gone somewhere else.
it's awfully hard to assume that any kid, even a coach's kid, will walk-on over offers of a scholarship from other schools. the money is one aspect of it, but it's also nice to know you're wanted (and expected to play) at the school you choose. smaller schools in the region (including those that produce the occasional NFL players, like UNO and NWMS) are constantly getting nebraska kids that NU would have loved to walk on.
as i said before, a kid is either scolarship material or he's not. if he is, you're jerking him around by not offering until other decent schools catch on. that might be the right way to play it on a video game, but real teenagers have emotions and real coaches have integrity. if you really want a kid, you offer him.
as for the grayshirt idea, there are reasons they're rarely used. the kid has to agree to delay starting college, which not every kid will agree to do, particularly when it is likely to be taken as a slight against his abilities. even if he will agree to it, it's really only useful if you actually think a kid is scholarship material and either needs a year to develop physically or you are just too full for the year. both of these may apply to cotton, if he'll agree to it.
the kid still has to be scholarship material though, otherwise you're just preventing a better recruit from getting a scholarship the following year instead of this year.
and for what it's worth, i agree that this offer would have raised a stir even if it weren't barney's kid. recruiting geeks have been throwing online conniption fits over offers to lowly rated home state kids for years now. some of them have been right, some of them have been wrong, but you can count on complaints. the fact that it's barney's kid just adds fuel to the fire, particularly for those that for some reason already dislike barney.
