We extract the cleanest possible signal of the afterglow component, and compare the temporal behaviors of the X-ray light-curve, observed by Swift XRT, and optical data, observed by UVOT and ground-based telescopes for each individual burst. Overall we find 62\\% GRBs that are consistent with the standard afterglow model. When more advanced modeling is invoked, up to 91\\% of the bursts in our sample may be consistent with the external shock model.
