I'm still praying that Sak/Mac pulls off something amazing at the TDL. Short of that, the biggest issue the team has had over the past 24 months ( aside from injuries obviously) is the awful 3rd line. So let's go backwards:
The 4th line of Cogs / Helm / LOC is one of the better 4th lines in the NHL. Leave it alone, especially since Helm will be fresh for the playoffs.
After that, might I suggest breaking up the stars in order to balance the lines and not get caved when the 3rd line is playing:
1st line: ERod - Mac - Nuke
2nd Line: Newhook - JTC - Mikko
3rd line: Landy - Meyers - Lehky (Or switch Newhook and Lehky to keep the Finns together.)
4th Line: Cogs - Helm - LOC
Malgin / LBN
I think we need to discard old notions of positions and lines, and consider - instead - the talent on the roster. Landy already has taken a lot of the Center weight from Mac. He could so the same for Meyers, whose speed could generate chances. Each of these lines has a workhorse (Nuke, JTC, Lehky, LOC) and a shooter ( ERod, Mikko, Landy, Cogs).
I'd also suggest using that 4th line to counter the opponents' 1st lines and simply out-hustle them, then let Mac & Nuke feast on 2nd lines, and Mikko have a field day against 3rd lines. At home, that matchup is infuriating. On the road, at least it forces the opposing coach to alter his lines in order to match 4th lines. This ought to distribute minutes as well. Cogs / Helm / LOC can easily play 15 minutes plus some PK, if it is planned well. One could make an argument that each of the 4 lines could get 15 minutes, with perhaps a sighting, here and there, of 9296 together gain if some fire power is needed.
The same can be said of the D. The bottom pair is going to have either Girard or Byram on it with EJ or a TDL replacement. That is not the typical 9 minute 3rd pair. Even Girard and JMFJ is good enough to play 15 minutes. This would be even more true is Sak/Mac decided to trade for a rental #3D which they would then turn around and trade in the summer for futures. But a D of:
Makar / Toews
New Guy / Byram
Girard / Manson
EJ - Hunt - Englund - MacPunchyface
A crazy good defense would also take some weight off Georgiev as well.
I love coming in here and reading hot takes. That said, JTC is in a contract year and playing like it. Most of the names mentioned as potential 2Cs (plus Kadri) have stats barely better than JTC. With the possible exception of Hayes at 50% retained ( which realistically is not happening) the players demonstrably better than JTC are off the market, never were on the market, or are recently injured ( Henrique and Monahan, though I submit neither is demonstrably better than the season JTC is having.)
I doubt any silver bullets are on the way. Bednar needs to think long and hard about solidifying all three lines and ABSOLUTELY CEASE the Bednar Blender.
