If the opposing team is full of loose cannons
Leswick - Sanderson - Perry
Will agitate and hopefully allow my excellent PP unit to their damage.
One of the most "peppery" units out there. If Corey Perry is the nice guy on a unit, they must be pretty unpleasant. Could be a weapon in certain matchups; I have rarely seen "pest" units as useful as this one.
Stewart - A very underrated pker who is also seemingly a strong defensive player who will help out defensively.
He's an underrated player. He was a pretty good ES scorer for a long time, but his career goes back too far for him to be included in overpass' numbers. I think Ron Stewart fits into the group of other great Toronto checking RWs like Nevin and Ellis. Stewart was probably the best PKer of the bunch, but the weakest even-strength player. He's fine at ES in a limited role.
This is generally one of the strengths of your team: it has depth of talent. You don't have obvious weaknesses, so Toe Blake can roll lines in the way he liked to run his teams - high-tempo, no shifts off. Your weakest forward is probably Ed Sandford, and 7 ES minutes/game of Ed Sandford is fine. He was a good, tough, all-around player who struggled with injuries, nice for a small-minutes 4th line role if you don't need the position to fill a special teams role. Went to four straight all-star games on merit.
Your defense is the sneaky strength of your team in spite of the flashy top-6 forwards. There are no obvious areas of weakness. I'm not the biggest Ching Johnson fan, really...I generally dislike defensemen who are as limited in terms of skating and puckhandling as Johnson. But defensively, he pairs very well with Harvey. Probably both the best defensive defensemen of their respective eras, they are the toughest defensive first pairing in the draft, bar none, and Harvey, alone, is enough for the puckmoving to be strong.
Goodfellow as an elite 2nd unit-across-the-board guy. Wentworth is a good #4, as good as guys (like Brad McCrimmon, as you pointed out) taken a hundred picks earlier. He seems to fit well with the more offensive-minded Goodfellow, and is properly playing at right D. How he fell to the 15th round is beyond me. It's not like it's a secret that Cy Wentworth was good.
Third pairing is strong, with Duncan a legit #4 and Rowe a pretty good #5 at this size draft, so both excellent in their roles as #5/6. Thing about Bobby Rowe is that his awards recognition (the PCHA all-star nods) are exactly the same as Lloyd Cook's, so he can't be that far behind old Lloyd, and he won more (won the Cup in 1917 in Seattle, and split the Cup in 1919...I consider this worth half a Cup to both teams, if you're asking). Third pairings matter a lot these days, and this is a quite good one. Again, the big strength of your team is depth. I don't see any bad minutes in your breakdown (except in goal, I guess, where you will almost always be at a disadvantage).
I think you have quite possibly the best skaters in the draft, which, I would add, you pretty much must have if you want to win (and simply having them doesn't guarantee victory...you could still lose to a team with a better goalie). While Hugh Lehman is not any worse than a handful of other bottom-tier starters in the ATD, he is still one of the 3-4 worst starters in the league, so if your skaters don't win it for you, you don't win.
A strong defensive spine of centers (Ullman, Weiland, Sandford)
Physical centers (Ullman, Sanford)
I'm assuming that both Sandford and "Sanford" here are actually Sanderson?!
