Nope.

In a 9F/6D league, you'll need premium defensemen in probably 4/6 spots.
But the other 2 defensemen you'll find you swap out with a hot waiver-wire player.
So there's no point in trying to obtain two waiver-wire value guys like Voynov & Josi.

If it was my team, I'd simply plug your 6th spot with a ho-hum defenseman and then swap him out when the season gets going.
Marleau has too much value in a 19-team x 9F league.
