Bertuzzi - Matthews - Domi
McMann - Tavares - Marner
Knies - Holmberg - Nylander
Dewar - Kampf - Reaves/Robertson

gotta have McMann with more of a playmaker than Nylander and Marner has had chemistry with Tavares in the past so the 3 of them seem like a fit.
there's also no way Kampf is coming out of the lineup. He's their main PK centreman. Dewar isn't much of a centre guy and is better suited for the wing.
the defence is just a ****show anyways but that's likely how it ends up.
Woll is more than likely the starter.. he's the calming presence back there and hasn't really done anything to lose the job yet

The Leafs have been able to work out their forward and their lines pretty well,,,shouldn't be a problem
The nine Dmen the Leafs have.....now that's another issue. When they are playing at their best, all nine more than satisfactory. But game to game.....you never know who is going play well or poorly.
Heck Giordano looked sharp in his first game back after missing a month on LTIR. Timmins has played OK to good when he's been in the lineup..
Maybe you dress all nine, and see who plays the best

11/7 seems like the route

Kinda strange.....last night Reilly, Liljegren, Edmundson out. Three guys you would think are locks to be playoff starters. But the Leafs played very well defensively....yea the forwards helped.

I'd run 11/7 also because it allows Keefe to be creative...

Throw out Nylander-Matthews-MArner one shift and then throw out McMann-JT-Knies after and then Bert-MAtthews-Domi, etc.

It also allows you to carry 7/9 defensemen (likely Timmins not getting playoff time but who knows)

It used to be that teams played almost exclusively 3 lines and 2 pairs of Dmen. Yep, I don't feel anything can go wrong with going with just 11 forwards.
