Yes, I'm aware of the problem. I started preaching about needing to get some bigs developing when I started 4 seasons ago. I'm waiting for something to come out U21 we can work with and will continue to encourage people to train players for us.
I haven't had a chance yet to scout around if there's anything new to get focused on but if anyone has a chance to develop a big I would highly encourage it.
I tried to draft a player to develop but only got a PA. I'll develop him anyway but he won't be able to get to the quality of our current players.
Unfortunately though, I think we're already facing a major void in our bigs in a few seasons.
