I don't agree. The standard of the average league one player isn't very high, and we've seen quite average players from our academy be released and go to other clubs and perform comfortably at this level.
So seeing that, if I were paying out the money I might say this player you want to bring in is actually not a massive increase in standard to player x in the academy therefore let use the money more sensibly elsewhere.
What we've not seen is many of our academy players step up recently, they should be if it's doing it's job so therefore 50% isn't a crazy figure, in addition are we honestly saying that one of the young forward wouldn't have shown more than Higdon (for example) for his wages and exposure to the first team. The academy have also had it quite cushy whereby they get their funding, there isn't any real pressure on them to produce and they always have the excuse that players weren't given a chance. Now they live or die by their results and the pressure is rightly on them to produce given the funding they receive.
I don't think it's an arbitrary figure, but I see nothing wrong with it as an aspirational target given what I've already covered about the general skill level of this league, but the academy does need to raise it's game and be seriously challenged to meet this target if they want to remain.
All this then frees up spending for where we really need additions, areas of the team where we don't have someone coming through, or somewhere we were clearly need a bit of quality. I'd much rather our funds be spent on those types of players rather than Joey Average who'll just come, pull a wage and not really move us forward.
