Your relying on too many young players to NHL ready in 1 year.
You might get 1 or 2 but 4 is not happening.

my only problem with this team is that you got a lot of players that havent played a full NHL season, which is a big question mark, look at WSH 4th line, Beagle, DSP and Stephenson (i think). a strong veteran pair with a rookie, they were lights out

IMO Johnsson, Grundstrom and Rosen will most likely make the team this year and will stay up with the big club for most of next year. Then by 19/20 they will all have a little more experience, as for Liljegren i don't see him having any trouble making the team in 19/20 after another full year with the Marlies.

About the 4th line i think the Leafs could add a veteran or two to give Max Jones and Bracco some more time to season in the minors. A guy like Josh Jooris who they just signed, or someone similar who can add experience and depth but also at a realistic price as the Leafs are gonna struggle to stay under the cap in 19/20. Which is one of the reasons they might need to play these guys while they're on their ELC's.

i didnt say theyd have trouble cracking the lineup, im just saying that having a veteren 4th line is big for a cup run. Beagle, Cullen, Lewis or Richards for the kings (i forget who played the 4th line) but all these team had veteran depth to win the cup. i dont remember a team that won the cup with rookies on the 4th line, correct me if im wrong please. im sure the leafs could find a way to bring someone in

I agree completely, I think the Leafs may have some guys like Hyman or Ferland who could drop down and play that role which might mean guys like Grundstrom or Johnsson get bumped up to play with Tavares/Matthews/Kadri which might work and it might not. I think Babcock will be trying alot of different combinations to try and find chemistry between players. If they dont do that, l think they could definately add another veteran 4th liner at a decent price maybe someone like Joel Ward, Lance Bouma, Brad Richardson (just a few guys i'd like to see them sign) again as long as they can find a way to stay under the cap which could be difficult for them in the 2019/20 season.

agreed, just looking a chicago, the whole "using ELC to fill out depth" hasnt work out well for them, but it MIGHT work for the leafs, but it might not.

Yah its not looking good for Chicago but i think with the likes of Matthews, Tavares, Marner, Marleau even Kapanen, (who could turn into an elite player in the league) these players will surround Grundstrom, Johnsson etc. and i think that they will have a very good opportunity to succeed in at least a top 9 role.
