Might be a little late on this, but Shabab Hossain on twiter posted this graph of expected goals and expected assists in the A-League this season. Interesting to see Sheridan above Willio in both categories - implies to me that Sheridan just got unlucky and he would have done a lot better had we kept him on.
The graph makes no sense to me without clarification whether this is actual (assists or goals) over expected (assists or goals)? If that's the case then it would be a useful graph. Sheridan outperforming the expectations by scoring one when he was not expected to score any.
However, if it is absolute values (expected assists and expected goals) then it is meaningless, simply reflecting Hossain's subjective ranking of the players. It may be the case seeing how highly Sheridan is placed, and how low someone like De Laet or Ninkovic are. Sheridan was expected to tear up the pitch, according to Hossain, better than Toivonen or Honda.
