Buying and Selling season

Just saw the Cards just traded for Ertz. So if it is trade deadline season, what if anything position wise should the Rams be looking for? Right now to me it seems you can't have too many quality corners but there are teams that need corners WAY more than the Rams do. Maybe another edge? If the Steelers become sellers maybe get Melvin Ingram. A serious pass rushing threat to pair with Floyd/Lewis might take the defense to another level. Maybe an upgrade at ILB, because covering the TE might be an issue come playoff time?
