I think its far more about defense. Hagelin Eller Sheary is your Crosby checking line. Oshie is to make sure McMichael and Sprong dont get in trouble.
Lavi basically has Oshie and Sheary to choose from for 2RW/3RW
Sprong-McMic-Sheary I don't think is going to create offense
Sprong-McMic-Oshie I think will create offense (Oshie's hands, creativity, hard checking and IQ being the big differential vs. Sheary being a little spark plug with less creativity/physicality)
I think defensively those lines would be about the same; with no Guentzel/Rust/Malkin, Lavi's main D worries are Crosby and Rodrigues (who has been creating a ton of chances); Carter's dangerous but invisible the last dozen games til last game w/2G... so not as much of a need to match lines tonight
Wouldn't be surprised to see Sprong and McMic both getting G's tonight with TJ as primaries on both
