A walk on offer or a guaranteed fall roster spot are not exactly things to brag about. As a matter of fact, it’s pretty common. There must be other schools that had given him a similar option or other schools that have shown interest even if it’s minor interest. The player should call those coaches only and explain the offer, but also let the coach know he would much rather attend their school if he can get treated as a preferred walk on. If he had no similar offers or interest then posting to media will do nothing to create interest.
