I think they're (we're) hoping one of Merkulov or Lysell surprises everyone and becomes an 18 - 22 goal guy -- that would be really helpful, but probably not likely.
I always play the "how many goals for each guy" game and I always overestimate, but I'll try to be realistic here:
Pasta - 47
Marchand - 24
Zacha - 23
Lindholm - 21
Frederic - 20
Coyle - 18
Geekie - 18
Brazeau - 13
Lysell - 12
Beecher - 10
Jones - 8
Kastelic - 7
That's 221 (and all seemingly attainable, IMO) --- without counting other forwards that will be in the lineup from time to time.
Only two teams scored over 300 last season.
Assume McAvoy, Lohrei, Zadorov combine for 25 and Carlo, Peake, Lindholm another 15 that's a total of: 261
Which is pretty solid, but not exactly the 87 Oilers, either.
(Again, not counting other forwards/defensemen)
