Weird. I do lots of rows, I would not say my strength suffers without direct work but size yes. Some people likewise claim they can do no direct bicep work (a couple guys, I can maybe dig up a name given some time, short philipino guy), but me I have to do direct everything - including neck.
While I get some stimulus with traps also doing some things, every friggin muscle in my body is what I'd call stubborn, minus maybe the chest and somewhat the arms.
