49ers OC impressed by Crabtree work ethic
San Francisco 49ers offensive coordinator Greg Roman can't be blamed for allowing his mind to occasionally drift to Michael Crabtree.The team's wideouts have struggled in the past two games as the 49ers have scored a combined 10 points in back-to-back defeats. The offense surely misses Crabtree, the standout receiver who tore his Achilles tendon in May. The team is hopeful he can return in December. He has been working on a side field during 49ers practices and has made nice progress.
