Six games into this homecoming season, Blackhawks winger Patrick Sharp was looking, feeling and sounding like his old self. He had two goals and two assists and was playing major minutes. He was flying around the ice, his surgically repaired hip feeling strong. He was effusive about being back in Chicago, playing with old friends on a contender. In the sixth month of the season, things are quite different. Sharp has been a role player at best, a spare part at worst. He has only seven goals and nine assists in 54 games and has been a healthy scratch a dozen times, including nine times in the last five weeks. With the Hawks in the midst of a youth movement, retooling around a core that no longer includes him, Sharp has been reduced to an afterthought. It’s hardly what he had in mind.
