When Tarvaris Jackson went down with a high ankle sprain in the Seahawks first preseason game last Friday, you knew they would have to add a QB. The days of each team carrying 5 or 6 quarterbacks in camp are long gone, and 3rd stringer R.J. Archer just isn’t good enough to be trusted as Russell Wilson’s primary backup should Jackson be out any longer than a couple weeks. B.J. Daniels was mostly a QB throughout college and his first couple of years in the NFL, but the team values him more as a potential WR and kick returner now, so he’s only an option in an emergency.
