Yeah I'm not necessarily leaping to any sort of defense here, I am just seeing your questions and believe I have an answer.
Which is, direct, focused, customized coaching. My assumption is Komisarek and the dev staff are going to work in lockstep with the training and coaching staffs, and certainly not in a vacuum.
I don't believe that the team staff has the ability to give custom catered coaching to each and every player while also creating a team game plan and structure, so I think the role of player development is to supplement the areas those coaches and trainers can't get to.
