The height is there, which typically means you get both defense and rebounding, but the two tallest guys are both wire frame freshmen.
We know Richie brings good defense, and some rebounding. Sounds like Demin will be OK defensively due to his size against other guards, but Catchings I don't know about on either point. As a freshman, it seems likely he'll struggle with team D. But we may indeed need his offense in a lineup with no Baker, Knell, Bosko, or Fouss.
