If you're an aspiring youth national team player currently playing college soccer and you take a look at the recent call-ups by Caleb Porter (a college coach, no less), it has to be pretty sobering regarding the decision to go pro soon or not. Porter called in 31 players yesterday - 20 "U23 only" players born between 89 and 92" and 11 U20 players born in 93 and eligible for both next year's Olympics and the 2013 U20 cycle. Of those 31, eight played college soccer and did so for a combined 15 seasons. None played four years and only one played 3. Here are the 8 - David Bingham - California (3 seasons) Joe Corona - San Diego State (1) Dilly Duka - Rutgers (2) Sean Johnson - Central Florida (2) Perry Kitchen - Akron (1) Tony Taylor - Jacksonville (2) Zarek Valentin - Akron (2) Ethan White - Maryland (2) And this is without several top players being called in, most of whom didn't play college ball. From the 23 pool, Freddy Adu, Juan Agudelo, Jozy Altidore, Teal Bunbury, Tim Chandler, Bill Hamid, Moises Hernandez, Zac MacMath, Jack McInerney, Ernest Nungaray, Amobi Okugo, Ike Opara, Emilio and Moises Orozco, Adrian Ruelas, Brek Shea, Anthony Wallace and Danny Williams weren't called in but all could compete for a spot on the Olympic qualifying roster or among those who go to London (assuming we qualify). Of those, the only ones who played college ball were Bunbury - Akron (2 seasons) MacMath - Maryland (3) Okugo - UCLA (1) Opara - Wake Forest (3) Wallace - South Florida (1 season) There will undoubtedly be current college players called into the current U20 pool. But, besides the 11 called in yesterday, they'll be competing with the likes of Vilyan Bijev, Luis Gil, Fabian Hurzeler, Juan Pabloc Ocegueda, Victor Pineda, Jonathan Top PLUS the 94s from the last Bradenton U17 cycle who are going pro (or have already done-so) like Marc Pelosi, Alejandro Guido, Alfred Korona and Mobi Fehr. Bottom line is that these guys who have skipped college soccer are going to make up most of the U20 pool (which in turn will form a large chunk of the 2016 Olympic pool). The college players born before 93? Forget it, they have next to no chance at the current U23 pool. But the current 20s, the 93s and (for next year) the 94s - they need to look at this and ask how badly they want to make the YNT and how that compares to their desire to go to and (in some cases) finish college and enjoy the college lifestyle. Because while guys like DeAndre Yedlin, Walker Zimmerman, Boyd Okwuonu, Jonathan Trapp, Nat Eggleston, Eric Miller, Andrew Wolverton, Bryan Gallego, Seth Casiple, Tim Parker and Jordan McCrary will get a shot with the 20s, they're going to be at a competitive disadvantage not being in a pro environment and the sooner they change that the better their chances of making future YNTs (and eventually senior teams) becomes.
