The short answer to your question : LAST
NCAA Recruiting is simple. Pitchers go first then middle infielders and Catchers . The money is ' In the Middle' . And in that formula , it is not spread out evenly . Pitching dominates recruiting .Go to any NCAA roster and you'll see 35 players and 1/2 are pitchers.
SS's generally go next . If you check Recruiting committs at PG , you'll see schools with 3 SS's in 2019 recruiting class. Why? Because as ILVBB pointed out above, a SS can move to 3rd, 2nd and any OF position.
Also, NCAA D1 recruiting is regional . The talent is regional . Look at the MLB Draft and you'll see that the bulk of talent comes out of California . Then Texas and other Southern States . Only the best of the best play D1 ball in the South and the West Coast. The South however, does like to recruit in it's own back yard . But even with that, it's tough.
The trick to recruiting is about finding the 'right fit' w/ Baseball, Socially, financially and most importantly academically .
You have to cast a WIDE NET. D1, D2, D3
Also, Foot speed in NCAA Baseball is HUGE. I understand your son is a big kid. But keep in mind , As a Sophomore he's not what he's 'going to be' . In other words , he's a 7.6 now in the 60. He can improve that. Will he break a 7? Maybe not. But a good track coach can shave 3 maybe even 4 points off of that time with just a few technique moves and some work by your son.
There is an old saying ' If you can hit, you don't sit'. That is true. If your son can hit , There will be a place for him but his recruiting interest might be slow.
If he's a good student, I would pound the SAT/ ACT work! High Academic schools are quicker to make exceptions for big bodied corner guys w/ pop . Also, as ILVBB said , Get him in front of Top D3 programs. There are a bunch in the South East . Emory and Rhodes come to mind.
The biggest mistake parents and kids make w/ recruiting is that they waste their time looking at schools they're not qualified to play for. Power 5 school? Yeah , contact them only if your kid projects for the 2020 MLB Draft because the guys they're looking at do!
My unsolicited advise is : Get those grades up , Hire an SAT / ACT Tutor and get a track coach from a local University. And Lastly , cast a WIDE NET w/ Recruiting . Don't focus on 5-6 D1 programs in the South. Clemson, SC, Georgia , Vandy all those schools talk to everybody but only recruit kids that project for Pro Ball. Look at North East Schools and contact 10-12 D3's
