No matter your opinion on Lavar this is an interesting article in general.

I know exactly what he means about people "connected" to kids and how they often act in their own best interests instead of the kids. not just in terms of steering kids to certain schools, agents etc. We had a guy on a UCLA board who's "connected" to the parents of one of the UCLA guys, he's a neighbor apparently. He has spent the last few years spreading rumors about how unhappy the kid is, he's transferring(he didn't), he's turning pro(he didn't), he's going to graduate early and grad transfer(he didn't). Over and over. to this day there are people on the board who hang on every word he says and insist the kid has been mistreated and dislikes the coaches and yet outside of committing to UCLA, virtually nothing he's said about the kids opinions have been borne out with actions. it's pretty clear those are really his opinions, not the player.
We had a case a few years back at UCLA with Tyler Honeycutt where his mom was openly posting on boards and she was bragging about how good he was and how Howland wasn't using him correctly and he'd be an NBA star. When he left everyone knew he wasn't a first rounder, she insisted he was, he wasn't, but got a guaranteed contract anyways, she came back to brag and say I told you so. He was out of the league so fast it made your head turn and of course we later found out the real reason he left early and she disliked Howland so much, she had been dealing with an agent since he was a senior in HS, and when UCLA found out, they told him to turn pro because he was going to be ineligible after they reported him to the Pac 12. Odds were one more year and he's a first rounder with a longer guaranteed contract so the small amount of money she took cost him millions.
