I just gave two instances of those players standing out. I understand there's the focus on the other guy on their line, because he's a new shiny toy, but it's not like he's creating those chances himself nor does it mean the rest of his line hasn't had their own chances.
Again, LaRose has been getting his own scoring chances and Jokinen's been playing the typical, silent playmaker he's been assigned to do. There's no finish on the line (as expected), but the chances are there. And like Boom Boom pointed out above, the finish isn't there for most of the forwards.
The biggest issue is the 4th line rather than the 3rd, IMO. Even in a shortened season, you can't run 3 lines an entire season, especially while putting the heavy focus on the top 6 as Muller has done.
I understand why he's done it, since our bottom 6 has been disappointing (to say the least), but if we're expecting the play from the team this early in the season is just rust, then when that rust shakes off, we need the players to still be...breathing...by the time the late season rolls around.
