Well i have not looked at this years crop of prospects yet. So 4 would be the bare minimum because I think picking a top 4 should not be hard and our first 3 games of the year are walks in the park. Which will give me time to make more decisions on personnel. Itll definitely be pushed up to 5,6 or even 7 by the end of the year.
A small forward type at the U21 level to me is basically either a shooting guard with good inside skills(Ulric Senneville, Hugo Moore, Joe Max-Phillips) or a center with good secondaries. What I was basically trying to say there is that id take a player who may lack a bit in primaries, but have really good secondaries over just another pure center or pure shooting guard.
