Take the Ipswich Town team that beat our kids in the 2005 Youth Cup Final. We had an uncommon number of players in that squad who went on to top-level competition. Ipswich didn't:
GK - Shane Supple. Played sparingly with Ipswich. Retired at 22. Making a comeback in the Irish league this season.
MF - Sammy Moore. Has had a fairly successful lower league career. Currently in League Two.
DF - Michael Synnott. Does not appear to have had a professional career.
DF - James Krause. Failed to make a first team appearance with Ipswich. Played non-league, appears to have retired.
DF - Michael Casement. Barely played with Ipswich. Has spent most of his career in the semi-professional Northern Ireland Football League.
DF - Aidan Collins. Barely played with Ipswich. Retired due to injury at 21, while playing non-league.
MF - Cathal Lordan. Seems to have played with Cork City. Can't find him now.
MF - Liam Trotter. Has settled in to a good career at the Championship/League One level.
FW - Darryl Knights. Cups of coffee with league teams have given way to a long career in non-league.
MF - Owen Garvan. Took this long, but we've finally found someone who saw quite a bit of the pitch for Ipswich. Even got two Premier League games with Palace, though he's now in League Two.
MF - Liam Craig. Has played his whole career in the SPL.
FW - Danny Haynes. Bounced around the Football League; now non-league.
FW- Blair Hammond. Does not appear to have had a professional career.
FW - Charlie Sheringham. Bounced between non-league and League Two.
MF - Ed Upson. Solid Football League career.
GK - Andy Reynolds. Does not appear to have had a professional career.
DF - Stuart Ainsley. Does not appear to have had a professional career.
The 17 players in their squad have combined for 2 Premier League appearances, as far as I can tell. Before the age of 30, I count 7 or 8 who retired (including the one making a comeback), and a further 4 who are plying their trade in non-league. That leaves 5 of 17 between the FL/SPL; Trotter, in the Championship or Craig in the SFL are playing at the highest level.
And that's not a random Academy...it's the Youth Cup winners.
Good example Schad. Very few make it.
