That's what I would do personally.
We can all cheer Toews 'career best' offensive output... the fact is, his previous high of 76 points had him at 12th in the league at the time. His new high of 81 points has him at 27th in the league. His actual impact on the game hasn't increased by way of his production, simply because the league as a whole is scoring more. He was actually more impactful scoring 66 points, dominating play and turning opposition top lines into mulch than he was scoring 81 points and basically trading chances every shift.
I'd tell Saad and Toews, 'your job is to keep the puck in the other guys end for the entire shift, wear them down, and win the goal differential battle. If that means you only score one goal, fine, just make sure the other guys don't score at all against you on most nights'. That's obviously easier said than done given the defense (and possibly goaltending behind them), but that's the mindset I'd want them in. Let the other lines handle the soft underbelly you provide. Just take the other teams best pieces off the board.
As far as who to play with them. That's tough. As far as FAs, it would depend on price and term, but I'd take a Zuccarello up there. Adds a scoring touch, but an underrated possession player as well. He's 31 though, so I wouldn't be comfortable giving him much term.
Edit: This is where I reiterate my sadness and frustration that didn't get a crack at Mark Stone. Cause he would literally be perfect.
