Yes, a Kleywegt plot for side chain rotamers. Possibly with the option to look 
just at hydrophobic or polar residues. Rotamer differences in poorly ordered, 
solvent-exposed polar side chains might not matter, but different rotamers in 
in the hydrophobic core of the protein probably mean a modelling mistake.
