Bob Condotta of The Seattle Times wrote Monday that coach Pete Carroll sounded "amazed" with the recently signed running back's ability to pick up the playbook.
"He ran the whole offense today," Carroll said of Jackson, per the newspaper. "I don't know how he got it all done, but he got it done in a day."
"I couldn't have picked a better place to come to," Jackson said. "... This is the best thing that could have happened to me."
