At the moment, the only thing I put on coaching is the PP system and the defensive zone system, which is looking a lot like Hynes-style chasing in the D zone. The PP looks like someone doesn't give a shit (Recchi?).
The rest of this, falls on the players. Just bad execution all around on details that should be crisp for NHL caliber players. They're freaking PROs, or should be, at least!
Making stupid passes for a third of every game, every couple games is on players for sure. Every game so far this season where they come out like this, passing is key noticeable aspect. Sloppy as shit. Watching other teams tic-tac-toe up the neutral zone or in the offensive zone OR we're running around like chickens with no heads trying to find the puck like a 6-7 year old town league who doesn't know how to work a defensive zone breakout. This is on the forwards and d making bad decisions with the puck, puck management.
Nico and Severson without their head up in key moments (Nico on a 2 vs 1, Sevs on the 6v5 or near end 3rd period had Tatar cruising to an angle pass almost free on net, and Sevs takes a shot that goes either no where or deflected). Nico and other players (Bratt), just telegraphing shots up in orbit in good look situations. Not blaming them on the game, but these are small details that I see. In general a lot of shots Devils take go wide, they don't even get em on net these days. Its hard to tell from TV if they're going for some sneaky deflection play, or just straight up bonking a shot.
Rushing pass plays and not making use of space when they have it is really hurting right now.
