Aha! True - but he reached higher than the value placed on him despite other (very good) options. Believed in himself and beat the odds initially placed on him.
I've seen Luke Maye play in person many times. The first time I saw him (not knowing his situation) I actually wondered, 'how did Roy Williams figure this out?' He didn't look like/move like a typical UNC freshman (or for that matter high-D1) basketball player and knowing the competition for a scholarship at UNC was steep - I wondered how he got to where he was.
Lots of baseball players fit that description. Small pitchers and catchers, awkward build or movement infielders/outfielders (see Hunter Pence), etc...
Heck, I'll throw our daughter into this who had very good HS grades, but not great SAT/ACT scores on math. She will graduate later this year in Mechanical Engineering with a very high GPA. Like Luke Maye, she works her tail off - harder than anyone I know.
You still have to be truthful with yourself - and high on that list is 'will you/your son be willing to put in the work?' And sometimes that won't be enough. But if you really are that, perhaps a higher reach is worth it.
Edit: Just say Coach May's post - articulated better than mine.
