Following on from an interesting discussion in the Darcy Tucker thread, two fellow posters (metaphorically) dropped the gloves on what turned into a discussion about coaches. Apologies for the following paraphrasing: 

Dan Winkler asserted that a coach has limited influence on his team and that players make the difference.

Jibbles asserted that a coach is a huge influence on the players and through good systems can equalize a talent shortfall (to a degree).

Personally, I agree with Jibbles. Herb Brooks' win in the Olympics epitomises that for me. I have also seen it very often in football (soccer). A new coach comes in and suddenly, the team starts winning, with exactly the same players.

However, I would be more than happy to be educated (either way) by the more knowledgeable types on here, because I am a bit of a newbie. Please discuss
