As the Saints try to deal with an aging defense and an untenable cap situation, several players who have been key components of the franchise’s recent success could soon be out the door. Per a league source, linebacker Will Smith and safety Roman Harper could both be cut, as soon as Wednesday. Smith has a cap number of $13.9 million, thanks in large part to a $10.4 million base salary. He tore an ACL in August and missed all of the 2013 season. If healthy (and there’s no reason to think he won’t be), the 2004 first-round pick could still be an effective 4-3 defensive end — possibly joining the rotation for a team like the Seahawks, if Michael Bennett moves on.
