Good thing we already have Bratt.
There's a reason teams very rarely overload with 3 stars on 1 line. It's overkill and becomes diminishing returns very fast. Too many mouths to feed, one puck.
We have the pairs already.
Jack-Bratt
Nico-Meier
chasing that tiny bit of increased production from those duos by trying to add a 3rd star is a doomed effort that will always leave you wanting more.
We've tried it with a number of different guys. It hasn't made a meaningful impact. The 3rd winger on Jack and Bratts line means so little. And since our PP1 is full, a bunch of value that a star adds in that regard will be wasted (but we'll still have to pay for it in trade and cap space).
You're paying star prices for a guy to fill a complimentary role (which will provide complimentary value). You don't want to be taking the puck off Jack and Bratts stick to try and let Tuch cook, because he's WORSE than them. You don't want the puck taken off of Nico and Timo's sticks.
Overloading your lines is only diminishing if your solely adding playmakers and not thinking about line synergy. It's also rarely done because it's hard to acquire 6 legit top players and keep them under the cap long term.
Look at some of the past Stanley cup winners they all had loaded top 6.
Florida with Barkov, Tkachuk, Bennett, Verhaeghe, Reinhart and the only "weak" link in Rodrigues.
Vegas with Eichel, Marchessault, Stephenson, Stone, Barbashev, Smith.
Colorado with MacKinnon, Rantanen, Landeskog, Kadri, Lehkonen and Nuchishkin.
Tampa with Point, Kucherov, Cirelli, Palat, Killorn and Johnson (with Coleman, Gourde and Goodrow on the 3rd line.)
Blues had Schenn, Tarasenko, O'Reilly, Schwartz and Perron all in their top 6.
Capitals had Ovechkin, Backstrom, Kuznetsnov, Wilson and Oshie.
Tuch doesn't need the puck constantly on his stick to provide a ton of value, He's a great finisher, plays great defense, doesn't need PP1 time to produce, Plays a ton on the PK, he's the exact type of player the Devils should be looking to add, someone that doesn't need to constantly have the puck on their stick to produce.
