don't think so. Sears' problems began long before Lampert. When was it, 30-odd years ago that they decided to re-image themselves as more female-friendly (discover the softer side of Sears) and downplay their strengths (Craftsman, KenmorI e)? Backfired big time...men didn't want to go to a womens' clothing store, and women didn't want to buy their clothes from a chain known for tires, lawnmowers and power tools.
By the time Lampert took over, it was more a case of when, not if it was going feet up. A shame, they were the Amazon of their day, but their eye was taken off the ball long ago.
