Monken already has said he wants defenses to have to defend the whole width and length of the field when facing his Ravens. It makes sense. The problem, though, is that spreading out defenders will force Jackson to have to make many more throws in areas of the field that have not traditionally been his strength.
I would want Jackson to do what he does best and not be boxed into any particular system. Having said that, the upgrades Baltimore made on the perimeter are outstanding and the value of these players has to be maximized. So naturally, the field will be defended differently, just based on the skill sets of the receivers.
