I'm actually on the fence over whether we need another starter-quality player to get into the tournament. I think this squad can probably make it. But I'd like to add some insurance.
At the moment our weakest spot looks like SF. We have some good players who may do a great job for us there, but there are also question marks. A proven starter there would go a long way toward setting us up for a good tournament experience.
After SF - and possibly even more important - is in the post. We all have huge hopes for Veesaar. But we have not room for error there. I'd love us to add a starter-quality center who might not ever start, but could pick up starter minutes playing with and behind Veesaar.
And my third choice would be a backup PG. We may have all we need but, again, there are question marks.
