Well I didn't have children those 'few years' by few I take it you mean 15 plus years ago!! Call it a convenient excuse if you wish, but I'm just stating my opinion that I think that KO time for anyone with young children is a non starter. I took my boy to the London game but I wouldn't entertain trying to keep him up for the later kick off. Obviously they can't please everyone though and I see what they're attempting to do regarding the tv exposure, time will tell if it is worth it.
One other thing to consider is that players in this league are mostly part time so will likely have work the next day, which might be a consideration for any sides that might need to travel such as London? Hopefully these things are being considered when schedule decisions are made.
