Lehner, Ullmark, Blackwood

Which two as my #3 and #4 G? I have Holtby and Markstrom as my 1 and 2... team in sig.

If one takes over, I may drop two and just run with 3 Gs... that would be ideal, but all three of these guys have competition for starts. One could argue that Marky has his hands full with Demko too, so I fear 4 Gs is my path this season.

Need quick advice.

Thanks!
