Duncan conducted himself incredibly well during a difficult season and his skills in developing Edinburgh's attack will play a key role next season and by bringing in Calum we are investing in a young, talented coach with a growing reputation."Director of Rugby Scott Johnson said: "It is important to outline our intention to improve results next season and build a coaching group around Richard to do that."We have been developing Scottish coaching talent like Calum and John in different environments and now they can bring their experience into new team set-ups, be it the professional game or the opportunity to develop the group and continue the upturn in results in the World Sevens Series."Edinburgh Managing Director Jonny Petrie said: "We are working closely with Richard Cockerill on the coaching team for next season and it is important they have a strong idea of what it means to play for Edinburgh to complement Richard's fresh direction."I'm looking forward to seeing the impact these new appointments have on our performances both in pre-season and into the new Guinness PRO12 and European Cup campaigns."I'd also like to thank Peter Wilkins for all his hard work and dedication over the past two years."
