Shaw is overrated because he simply is not this magical defenseman coach that some Philly fans think he is. First of all Drysdale, Seeler, Ristolainen and Sanheim have not left. They're still here. All that they have done is put a defensive structure in place. A conservative defensive first system that is not conducive to the modern day NHL and the attack, transition league that it is. It's the equivalent of playing zone defense as opposed to man to man in basketball. When or if they bring in a new coach who hopefully installs a modern day aggressive system and style of play. Players like Ristolainen, Seeler and Drysdale will be exposed for what they are. Ristolainen and Seeler are at best 3rd pair NHL defenseman and Drysdale is an offensive defenseman who is not very good offensively and poor defensively.
