I would say either Filpulla or Gagner help you the most. Gagner is pretty hot right now but he is streaky. Filpulla is the same way but doesn't go quite as cold as Gagner does.
I would say take Filpulla if you want sustained lower production over the whole season.
Take Gagner if you are willing to watch him put up points in bunches then go cold for a few weeks.
If you prefer to take a winger, Hornqvist is your best bet. He is starting to turn around now and should produce well for the remainder of the season.
Without me, it's only "aweso".
