I could see him developing it in the coming years once he's up in that 220+lbs range that he should easily hit. I'd expect to see that line in the coming years, but I'd be perfectly fine with Lucic-McDavid-Eberle for the next couple, especially if they can get some chemistry. Could easily see all 3 of Lucic, Eberle and McDavid flirt with 30 goals if that line clicks early on and if the power play is top 10 in the league.
I honestly can also envision Puljujarvi running the 2nd line in the future with Draisaitl similar to what Hall did. In my mind Puljujarvi can be the line puck carrier just like Hall was, and actually has more dominant physical tools if he develops properly.
We'll see if Pulju can click right off the bat with a guy like Drai or Nuge as his centre, and its entirely possible that we might never need to put him with McDavid at 5 on 5 regularly unless we're trying to tie up a game. Thats one of the main reasons I've never been as down as some fans at the loss of Hall, is because I envision Puljujarvi being the same type of player in terms of driving the play forward and carrying the puck.
My dream scenario right now for next year is to see Pulju start the season on a line with Dra.
I really hope he makes the team, makes it by earning it and showing he is ready, if not then AHL is fine.
The team and situation has turned 180, I look at the situation in Edmonton as pretty perfect for forward prospect to jump in, they can shelter him, while lining him up with another 3rd overall pick from few years ago.
They can give him easier minutes to develop his game, chance to play in offensive situations thanks to playing with highly skilled C and let him play his game, let him use his strenghts, confidence is everything for prospects.
He wouldn't be put in a role where he'd be asked to play with 4th liners, in a defensive role like Rantanen was last year, he was playing under 10mins per game with 4th liners who had no idea what to do with the puck, no icetime in special offensive situations.
I'm also guessing Puljus shot could be an asset for powerplay, they'd have a right handed shooter with a 100mph shot, while also bringing high level playmaking skills on the table.
Edit,
And I could see Pulju return the favour for Dra, give him a winger who has elite potential. Winger who works all over the ice giving 100% in every shift and who skates like Hall.
Pulju was the top possession player for Karpat last season.
I don't necessarily think there is a "one size fits all" approach. I mean, the Pens just won with 3 scoring lines. I think it's more about playing to your strengths.
If we load the top 6, then Letestu and Lander? would be our 3rd and 4th line centre. Our strength is our depth at centre mixed with size and skill at the wing. Having RNH and McDavid at centre also helps shelter Drai. To me, a top 9 approach balanced with size and skill plays to our strengths better.
Lucic-McDavid-Yak
Pouliot-RNH-Eberle
Maroon-Drai-Pulju
Hendo-Letestu-Kassian/Pak
Chicago also won the Cup with Sharp-Vermette-TT being their 3rd line, it was a difference maker against Tampa.
