I don't know how we can just write off Broberg's development here. Now, I'm not saying our coaching staff worked magic on him, but you are way overrating what he did in the playoffs. His actual results were very good, but his xGF% was 34.87%. He had a tremendous amount of puck luck in the playoffs, and this season his expected results are solidly over 50%. To say that it was basically a given that Broberg would excel like he has in a 20+ minute role is kind of silly.
Now, I don't think our coaches turned him around, I think he just needed the right situation, but to say our development played no part is also kind of silly.
