Agree with this. Those saying guys can't maul run blocking in a ZB scheme make me laugh my arse off. Its still run blocking, if you aren't getting nasty and 'gaining ground' then you are doing it horribly wrong. Watch film of our OL the last two years, watch the interior line and how they move and get down field. They have the size of gap or power blockong scheme guys but they can move. Last couple years in Seattle their OL was terrible, but look at what Cable was working with? Last three years their fans have been screaming for OL help in FA and Draft & all three years they did very little. Throw in an injury or two and Cable found himself working with arguably the worst OL group in the NFL.
