Hard to opine on players when we haven't seen them play.
Of those I've read about and seen clips on, I think Edmondson is the best fit as a guard. Buljan the best fit as a big. Zalbas is also very intriguing, but I don't think he'll have the grades. Same for Burton.
Notwithstanding what folks have said about Bonneau, it's again hard to judge him without having seen him play, but he's got some incredible stats in terms of scoring and shooting, which are two things that we need.
All that being said, I'd use up at least two if not three of the ships. Saving them for the next coach does Norm no good, as he's got to win now and a new coach (if there is one) can always make his own roster decisions going forward.
