Thanks, everyone. As usual, very thoughtful, and helpful, responses.
Old School: our situations are remarkably similar!
JBB: I think 2019 will benefit from the good will 2017 has built up over the last year, especially with a couple of coaches who eventually said no, but were unusually generous with their time even after they told 2017 he didn't fit their plans.
2019: I think they ARE different players, but they have similar academic/baseball goals so sometimes I don't distinguish the differences their futures may hold. And I don't want to get my hopes up to much!
I do think Cabbage Dad's comment about it depending on how good 2017 is, is a very clear insight. When 2017 started this process I had NO doubt that he would be extremely competitive at ALL D3 schools, and that it would be easy for him to find a spot. When some D3s started to say "No, thanks" I was surprised. I thought the possible reaches might be Ivy league schools, not D3s. So I ended up learning a lot more about the D3 landscape and how varied it is. 2019 is aware of what's ahead and one concession he's made is to drop soccer to devote more time to lifting and conditioning.
I'm still not sure that the schools that said no actually have better programs than the schools that offered him spots, but I was grateful that they were all, every one of the D3's anyway, exceedingly clear about where 2017 stood with them. The schools that said no, said they were looking for guys who could outright mash. My guy is a contact guy, not a masher, so there was an obvious reason they didn't pursue him. I do hope those schools looking for mashers might see what they need in my 2019. He's going to give them a shot, anyway, and it won't matter to him if they said no to 2017.
A little bit of clarification: I have already heard from some objective (theoretically, anyway), and knowledgeable local baseball folks that 2019 is more projectable than 2017 is, if only because of his height.
I'm just trying to be objective. 2019 doesn't stand out from 2017 to me, but he is still growing into his body, he's working hard in the weight room and he's pretty driven.
His last name is distinctive: Smithfield-von Rohrkamp, so coaches might remember it. J/K, but it IS unusual enough that they'll remember it if they aren't brain dead. He has the same academic goals as his brother: using baseball to get into the best academic school possible, so it looks to me like he'll take a similar path at this point.
Fenway, I'm comfortable with this being my son's journey, not mine. If a school is a good fit, I'm all for it. I didn't meet a coach that I thought poorly treated my 2017. There was some miscommunication along the way with a school or two, but frankly, I'm surprised there is not more. There are so MANY moving parts in this process that I think it's a minor miracle that players who are solid talents (but not d1 studs) find places at all. There are a LOT of solid talents; I'm immensely grateful my 2017 found an exciting place to play, and, obviously, I'm hopeful my 2019 has similar results.
Gov, RJM, Branson, and JCG: I think we won't mention 2017 and we will just let the recognition factor, if there is any, be organic and up to the coaches. I don't know how good 2019 is, other than if he keeps his grades up, I do believe he'll be an interesting player for some high academic D3. Ivy or Patriot League is another question entirely and I've decided I just don't know enough to understand where he might fit there.
Thanks again, everyone. Really appreciate your help.
