He's very typical of what most teams are playing at the four spot. A little taller and not quite as quick. You're arguing to move him down the positional spectrum to guarding even smaller guys than this on the perimeter?

Just off the top of my head in conference.

Houston has the heavy D focus, so they have two non shooters out there a lot.

Everyone else:

ISU - Momcilovic
Baylor - Bridges
TT - Darrion Williams
KU - Adams (this was a tough matchup for Noah, and it showed)
TCU - Obannon/Coles
Texas - Disu
OU - Soares

...

With the exception of Disu and Adams, most of these guys are perimeter shooters/slashers. They are all smaller and aren't posting. Noah held up fine against Disu all things considered.
