I doubt Keefe goes with 11F/7D come playoff time. If the team is healthy I don't really think there is a "missing" forward. That line-up would look something like:
Kerfoot-Matthews-Marner
Bunting-Tavares-Nylander
Jarnkrok-O'Reilly-Lafferty
ZAR-Kampf-Acciari
Lines of course could/would be juggled a bit but that's 12 forwards strong (still looks like a group that could have used another middle-6 winger, but alas...). Knies would be the wild card. If he blows everyones socks off I could see ZAR getting pushed out of the line-up with Lafferty going down to the 4th line.
But I don't see ZAR coming out to bring in a 7th defencemen. It just makes sense to do it now with ROR out, the defence group still needing time to settle in and figure out where everyone fits, and to give the team experience with the format in the event that circumstances change and it makes more sense to go with 7D.
With that said, I think this attempt at 11F/7D has gone much, much better than it has when Keefe tried it in the past. For starters the 7th defencemen is generally a lot stronger than those last attempts, and is someone that Keefe trusts playing a lot more. I seem to recall the 7D before being someone like Liljegren early in his career or another rookie defenceman. And the forwards make a lot more sense since instead of say Spezza-Simmonds being the duo needing a rotating forward it's more of a 3rd line duo, which gives Matthews/Marner/Nylander or whoever gets the extra shift something more to work with.
