I can't understand what they're saying (assuming it's in Spanish) but there's some impressive game footage of Aldama here, both during his games with Loyola as well as international competition at the U18 Europe tournament, where Aldama won MVP.
Usman Garuba was Aldama's teammate on team Spain at the tournament, yet Aldama won MVP, not Garuba. Garuba is projected to go in the 12-22 range of the draft, so it makes no sense to me why Aldama is projected in the 45-60 range..he could be a steal if we grab him at 45..
