Narrative:

Given crossing restriction 10 north of hiely at 13;000. Got behind on decent; asked for relief; controller gave us a heading and descend to 13;000. Entered moderate chop; overspeed of 5 knots or so clean configuration. I was pilot flying; rushing to comply; along with chop; I got behind aircraft. I need to do a better job cross checking the automation against what the restrictions actually are. I was trusting in the automation too much for when to start my decent. As a result; I got behind and rushed to comply; or attempted to do so; that combined with the moderate chop and several heading changes; the overspeed occurred.
