This could easily be the same problem that we had when retaining the likes of Holmes, Hepburn, Williams etc etc etc.
Lots of people go on about how players who left our academy are now big names, however, in most cases it's taken a few seasons before they've become premiership players and then again for them to become established.
Given our previous precarious financial situation, we weren't in a position to take the gamble that they would become top players, and also some were probably nervous about staying with us under those circumstances.
While a lot of the talk is about how promoting academy players is the only way to remain sustainable, it's still a major risk, and one which can prove expensive.
The salary cap is a problem for most teams, releasing a young player who may or may not make the grade allows the clubs to either sign someone else, or add a little bit to a couple of existing players salaries when their contracts come up for renewal.
Even a successful academy player is going to want to earn their money if they make it to the top, so eventually, if they're good, they're probably no cheaper than anyone else.
