There's no way in hell that's his, nor any other developing players fault. there are players on the list that are being looked at by club and supporters. I'd suggest there's enough dead wood on the list to get rid of before the potentials get culled. There's enough space on any list for a good team, and a development base, hell, you can't have a list of superstars under the salary cap (I guess depends on the club....). It comes down to how well you develop and manage the young talent. That's our future, not the current 25+ group - their job is to get us ready.
I want to see the Harmes', Whites, Kings, etc debut to see what they've got, at the expense of the usual suspects, but I'm happy to defer to the experts and wait patiently until the time comes. Personally, I think all 3 will be regular 22 come the end of 2016.
