Do the stellar kinematics suggest it is a natural extension of the outer envelope of a BCG, or, is it part of the cluster? We will examine each of these questions with WIYN SparsePak IFU-like observations of a unique sample of 23 low redshift galaxy clusters. We analyze the spectra of BCG cores, and for the first time, large samples of BCG+ICL spectra. We present stellar ages, metallicity, and velocity dispersion throughout the galaxies.  These direct measures place important observational constraints for models of galaxy and cluster evolution.				</div>			</div>		</div>	</div></div>
