Maybe the early goal threw us but I don't think showing them respect (or not enough) came into it at all. Kids have energy is a bit simplistic though. It's the end of a long season, tiring week behind them and while they have energy, they're not physically equipped to deal with lots of games back to back like the senior pros are.
On that sort of subject, this run we have coming up worries me a tad - Saturday/Wednesday/Saturday/Tuesday/Saturday/Tuesday from here on in if I remember rightly, and with the squad pretty stretched through injuries and a few players looking a bit leggy already, it might be a tough ask and we might see a few more games like today.
