Your quotation.....

"Her husband, among various physical accomplishments, had been one of the most powerful ends that ever played football at New Haven — a national figure in a way, one of those men who reach such an acute limited excellence at twenty-one that everything afterward savors of anti-climax. His family were enormously wealthy — even in college his freedom with money was a matter for reproach — but now he’d left Chicago and come East in a fashion that rather took your breath away: for instance, he’d brought down a string of polo ponies from Lake Forest. It was hard to realize that a man in my own generation was wealthy enough to do that.

Why they came East I don’t know. They had spent a year in France for no particular reason, and then drifted here and there unrestfully wherever people played polo and were rich together. This was a permanent move, said Daisy over the telephone, but I didn’t believe it — I had no sight into Daisy’s heart, but I felt that Tom would drift on forever seeking, a little wistfully, for the dramatic turbulence of some irrecoverable football game."
