Ok you team is in first for a reason. Now, this deal on the surface is tempting with the addition of AO but as you said...
AO >>> Alfredson
but
Carlson <<< Green
Kipper <<< Lundy
The kicker for me is the fact that your goalie stats are 4 of 8 scoring categories. In other words you need goaltending to be competitive. I'm not sure if the addition of AO makes up for the loss of Lundy.
As much as I would hate to say this you may have to pass on this one.
Good luck with your choice
Cheers!
