SANTA CLARA, Calif. -- We all know about the heated rivalry between the San Francisco and Seattle Seahawks.We know about the roster poaching, allegations of the postgame shenanigans and as Vernon Davis reminded us this week, "they don't like us and we don't like them."One of the men in the center of the rivalry, 49ers coach Jim Harbaugh, however, had nothing but glowing things to say about the Seahawks in preparation of Sunday's game against visiting Seattle.
