The youth development can be quite frustrating, but if you do get a good pull, it can change the whole game for you. I drafted N Sutton (in the NZ team now) and ended up selling him for around $500m. This allowed me to purchase some slightly lessor players in key positions and really turned my team from a bottom half Div 2 team to a top 6/challenging for promotion team.
My YD is 9/10 now and I still usually only get the 2* - 3* pulls, which usually get fired. It is a bit of a gamble I guess.
