Futbol,
The 3 players that went to DSC were on the 90 Gold, Lundy and Khoury from the start, and Twohig (from GA) was added over this past summer. I've seen Twohig in an AFC, Cobb and now DSC uniform over the years. All of these players are 1990 age ODP players, I think. I'm not sure about Twohig.
OTF,
Yes there are two former 90 Gold 1991 ODP age players that are in Mt Pleasant now. One of which is a 1991 State ODP team player. The other has been a 1991 State ODP player in the past.
Of the roster listed, I know of at least one 1992 ODP State Team player, and 1 1993 ODP National Team player. As far as physical maturity, there can be some big gaps between 13 or 14 year olds and 16/17 year olds.
With the 1 national team player, it's good to see player development being put ahead. Even though he's already played in 7 matches in the SCSCL, apparently, unless there's a loop hole in the rules, he's going to forgoe the rest of the SCSCL season to participate with the academy.
