I always thought Nutten and McCoolum (and Grut) were back ups...but, because of Martz, they didn't need to drive block, so
they were good enough......oh boy, I opened the GSOT can of worms, arghhh!

Well, we know Blythe is a backup guard, and so was Allen at center, and yet the Rams did pretty well last year....so, maybe McVay's system does something like Martz's....
