The aspect that interests me most is our beatup oline against their beatup dline, anyway...CN vs RW won't ever be seen on the field, so, not much point in discussing it anyway, imo.
There we go! Yes, it may all come down to the lines. Both QBs can break containment, so it may be a game of clouds of dust decided by big plays.
I do think our D line over your O line is a bigger differential than your D line over our O line, This is in part because we get Carpenter back! Road grader! He won't likely start, but in Seattle's schemes that doesn't really mean much for our lines. They do heavy substitution in the best of times.
Honestly, if Carp were ready to start at RG, I'd upgrade our O line to very good, almost excellent. If McQuistan took over at RT, this line could become elite.
