Just looking at the squad on Transfermarkt it shows 27 players with an average age of 26.1 yrs. Take Didzy (37) and Slocombe (36) out of the equation and that average age get's closer to 25. We have 14 players in the squad who are 25 or under, those being:

Stone 25
Bedeau 25
Macari 22
Ness 22
Johnson 20 (Loan)
Abbott 19 (loan)
Hinchy 21
Robertson 23
Grant 23
Tsaroulla 25
Whitaker 21
Sanderson 18
Jarvis 22
Martin 23

Even without the loanees that a decent crop of youth/younger players on the books and aligns perfectly with the Bros model.

Just to repeat this was the information on Transfermarkt and not my own analysis.
