Rielly will never ever move to right side. He does not have da hands to make it work. Dermy has ability because he has learned how to make all the adjustments over many many many years. It is very hard for any guy never mind an NHLer AHLer OHLER to make switch. From turn, to pivot, to positioning of addressing puck and angle of stick for passes etc. It takes years and years of REP to learn it. It is a practice made perfect game defense. Good news is Dermy will have very few issues learning it except pace of game. He wants to sign, Leafs want to sign him and he will play right side next season with either Muzzy likely or maybe Rielly.
