NEW ORLEANS -- A lawsuit claims the newly constructed $2 million Uptown home of Saints defensive coordinator Rob Ryan is sinking.

NOLA.com/The Times-Picayune reports Ryan and his wife filed a lawsuit Monday against the developer, builder and an engineering firm.

The lawsuit claims the ground is shifting badly beneath Ryan's house, which wasn't built on pilings or sufficiently spaced footings despite New Orleans' notoriously soft soils. An engineer hired by the Ryans determined that key joists throughout the house also are overloaded.

The lawsuit names developers Jim and Catherine MacPhaille, contractor Southern Builders of Louisiana, and two engineering firms as defendants.

In his statement, MacPhaille said the house is structurally sound, and that Ryan is using the lawsuit to manipulate the builder to buy the house back at an enormous profit.
