TRIGGER WARNING: These are just opinions and my generalizations. There are always outliers. I'm sure whoever gets mad at my opinion it's because your kid is the outlier and the only one different. These are all related to boys.
Also, I'm not saying any of this is morally right or how things should be... but this is the reality that I see. I ain't the enemy, just calling what I see. To be honest, I detest most of it. So... this is just what I see, in my experience. You don't like it... yeah, neither do I. You disagree, cool. Move on, I'm good.
1. Are college scholarships given to a lot of southern CA soccer male players more so than from other states?
Yes, statistically, more soccer players come out of Southern California than any other region.... around 40% of all USMNT players have ties to SoCal.
2. How and when do you judge if it’s something attainable for your son?
I have coached players who have gone on to play in the MLS. I also know numerous players and close friends personally who have signed homegrown deals and or are playing USL, USL-1 or MLS Next Pro. I also watch a ton of MLS academy games.
The vast majority of players who have a shot at becoming professionals are or were playing up 1 to 2 age groups in the most challenging available league and still dominant. If you are playing your age group and good, congrats. But less than 1% of all players become pros and less than 7% become collegiate athletes at any level... so you don't need to be good in your age group, you need to be better than your entire age group and good above that.
My top advice for any young parent who recognizes any level of natural ability in their child to, as early as possible, move them up an age group. Never play with your birth year peers until you have hit the highest level you can... and then work to be pulled up one more... ha. This is true in MLS academies. You have 2009s playing u17 with 2007s. You have 2008s playing NextPro with u23s. You have a 2006 starting last week at Columbus Crew. Even America's next great hope Cavan Sullivan is a 2009 playing NextPro against u23s. More than half of all MLS u17 (2007 year) teams are 2008s playing at least one year up. Moral: Be the best amongst those older...
If you are not playing up 1-2 age groups by 16, I would recommend college as the primary focus and goal. Sure, keep the pro dream alive whatever but plan that it will likely occur after college, not after high school, if at all.
Based on the last 3 years of recruiting classes that I've seen...
If you are dominant and starting at an MLS academy, I would think top D1 or any option.
If you are very dominant at the ECNL level and also at a powerhouse high school, then I would think top D1 or any option.
If you are playing MLS Academy and aren't dominant at the MLS level, I would focus on a second tier D1 or D2.
If you are starting at a good MLS Next but non-MLS academy (TFA, Strikers, etc) or MLS Academy kids who aren't dominant, I'd target second tier D1 or D2.
If you are ECNL in your age group and starting or getting minutes... JuCo, D3, D2 or NAIA.
If you are at a lower MLS Next non-MLS Academy, JuCo, D3, D2 or NAIA.
3. Did I miss something along the way about preparing kids to get scholarships that these parents had?
Unfortunately, quite likely. MLS Academy rosters are full of parents who either really know the system, found a trainer who was well-connected and very good and/or are former college/pro athletes. Fair or not, it is largely a closed system of elite players who all grew up together or players who can afford the very high quality and highly technical connected trainers.
4. Do boys playing on MLS next teams and ECNL only get scholarships and not the ones playing EA?
See previous post about soccer being an equivalence sport and the 9.9. Unless you are a US Youth national team level player, you are NOT getting a full ride to a D1 school. Those are rare and used to entice a player who could also go professional. Most PSA (potential student athletes) will get some sort of stackable scholarships. Thus, the higher your grades or other scholarships, the more attractive you are to a coach. You will also likely only get a smaller percentage your freshman year and then it goes up each year. This rewards your likely older starter as well as motivates players to not go into the portal.
Also, I listed above where I see most of the scholarships falling. Early in the recruiting season, you will see a lot of scholarships go to the top ECNL players and non-MLS Academy MLS Next players as the MLS Academy players are weighing their option of college vs NextPro.
FWIW, I rarely see an ECNL player sign D1 who isn't also at a power-house high school.
5. And if this is something you want for your kid to have a shot at do you need to do extra trainings etc.?
Sorry but 100%. The benefit is your top players don't pay for anything... gear, travel costs, food on team trips, hotels, club fees... nothing, but then the parents are spending the money on extra training to try and get an edge. If you do what everyone else does, you will be what everyone else is. Also, there are some really great trainers... who have no connections to top teams. So, who you train with matters. Find out who else trains with them. You can look at the LAG and LAFC rosters and see the products of about 3-5 different trainers... BigCat, YPS, Mike Chapin, ProCarthy, First strike... etc.
Again, other great trainers out there, but in a closed system, it's who you know.
All of this is a meat grinder of a system. My advice is to protect the joy of soccer for your kid. Don't push so hard towards a goal of scholarship or a certain skill level that you crush the kid along the way. Some love it... more flame out and then succeed emotionally and soccer-ly at a lower level (with a lower result).
Don't forget about education. Most of the MLS academies now require online schooling. There are big social sacrifices made so make sure you weigh those out.
