I find it hard to believe that a HS player doesn't want it to be known and probably couldn't keep it under his hat anyway.
What he said.
The 1st person to announce commitments is often the recruit themselves. I think in this day and age of social media, etc. it'd be darn near impossible to have a silent recruit. Though, it does happen from time to time still.
KU was able to do it with Kerr Johnson, but it's still a rare thing to have happen.
I guess KU could try and do that if the recruit will cooperate.
I really don't think there's some creative way to keep poachers at bay, other than to keep selling the recruit on what KU offers them. Keep in contact with them and build that relationship and trust as strong as possible. Some coaches are better at that than others.
Also, getting the parents(moms especially) on board as well is key with a lot of recruits.
A lot of HS recruits mostly think of the here and now and as you said other teams come in and negative recruit against KU successfully sometimes because of the here and now nature of a lot HS kids. Winning more games and keeping the program on the upswing is what it'll take to keep some recruits from being flipped.
I also think that seeing 2 Bama guys transfer in, as well as seeing very highly rated recruits like we've got currently committed also helps out a lot with HS kids who are of that hear and now mindset. I think that recruiting momentum will help keep guys committed, but every team has guys decommit almost every year, so it's not bullet proof.
Lastly, I don't think we've failed in recruiting good DL and OL over the past couple of years. Yeah, we lost a few, but we've also gotten some good ones. Guys like Adeniji, Ribordy, Baldwin, Armstrong, and Wise all come to mind immediately.
