I agree with that. I used to do real estate finance and anchors- particularly ones in older malls- often have minimal net direct economic benefit to landlords. The value they add is the shoppers they allegedly draw to help the in-line stores. For Eastland, Dillard's apparently isn't doing that well, and that Belk's doesn't seem to be thriving, either. Thus the mall's owner isn't directly making money from the anchor leases and the mall's in-line tenants probably aren't getting much from them, either. Thus if the department stores could be replaced with anchors that appeal more to the neighborhood's residents (e.g., maybe an Old Navy, Steve & Barry's, Magic Johnson Theaters, etc.?), both the landlord and the in-line tenants could be a lot better off.
Oddly enough, some stores will stick around in an unanchored mall. Greenville Mall lost its JBWhite/Dillard's, Proffitt's/Parisian and Wards anchors over the past four years but still has a few stores (Eddie Bauer, Finish Line, April Cornell, etc.) left in the inside. I don't know how on Earth they survive, but they are hanging on.
