LOUIS, Mo.

    — Todd McLelan is trying to make the Blues’ top six more effective without O’Brien and doesn’t think the loss of O’Connor will hurt the team too much.

    McLellan, the head coach of the Chicago Blackhawks, said Monday that O’Reillys absence means the Blues are likely to have to make roster changes to get to the playoffs.

    O’Connor left the team on Sunday after going 0-for-3 with one goal and four assists in a 3-2 loss to the Dallas Stars.

    McLeod says the Blues will continue to add players to their bottom six in order to have more scoring punch in the top six.

    He said O’Leary has been “really good” in his absence, and it will take a lot for O’Keefe to be more effective with his scoring.
