He started off in that direction, buying Lands End and making a bid for Restoration Hardware. I recall an interview or press release laying out a vision for Sears as a "store of stores" that showcased iconic American brands - Kenmore, Diehard, Lands End, etc.
Somewhere along the line that dream died, and the cash flow was used mostly just to repurchase shares while letting the stores Languish. A bunch of concepts were tried in a handful of stores, but none promised an attractive ROI so they were dropped. Bruce Berkowitz is another investor that used to get compared to Buffett an awful lot, and tied his fate to the Sears project. He's still buying more shares and saying he sees value there.
I don't really have a point other to say that investing is hard, and identifying talented value investors who will outperform in the future is even harder. Whether this was a dumb idea all along, or a poorly executed good idea is tough to say.
