I think that's fair. Matas has a chance to be a really good player, but Allen was a different level of defensive prospect. People forget Allen was a one-and-done freshman who went in the first round largely because NBA teams already knew he could rebound, protect the rim, and defend at an NBA level. I'd probably put Matas in the Hayes/Bamba/Myles Turner discussion as a prospect, but Aldridge and Allen feel like a tier above. If Matas ends up getting drafted that high, it'll be because teams are betting on his versatility and upside, not because he's already the defender that Allen was coming out of Texas.
