Had an interesting conversation with a saleswoman the other day regarding watches. I remarked that it’s intriguing that so many watch manufacturers have tennis players for pitch men – and women. You don’t see as many NFL players representing watches.

That might seem counterintuitive since tennis isn’t played against a clock – although it certainly records the time of each match, whereas football is played in four 15-minute intervals, albeit with lots of timeouts and a halftime. Shouldn’t Peyton Manning be the spokesman for Piaget?

But a watch – a gift of time – is a classy thing, she said. Tennis players are classy, she added. By implication, football players are not.

It’s always dangerous to generalize, of course, but there is some truth in what she said, as I myself have pointed out in this blog. Tennis has prescribed rules for deportment and an intimate, relatively quieter setting – though it can get pretty loud – that underscores infractions. When Novak Djokovic sarcastically applauded the crowd as it applauded his double-fault in a semifinal against Kei Nishikori at the Barclay’s ATP World Tour Finals in London Nov. 15, he was quick to blame himself for letting the crowd get to him and losing his concentration.
