A Seniors tour or Legends tour in tennis, depending on how you look at it, has the potential to be quite successful. The issue that would surround it is sustainability.

The crowds have flocked to see past legends play, and the Australian Open in particular has staged some memorable and successful Legends matches. There’s something that people love about the idea of seeing John McEnroe playing Pete Sampras, and seeing players that the younger amongst us never got to see is certainly a great thing.

As I say, the issue here would be sustainability. I have no doubt that people would love to see this happen and see these players, but how long could a tour survive?

The expense involved is the first concern. For the tour to come about there needs to be a wealthy backer and an enormous amount of sponsorship. Venues would need to be booked, prize money good enough to make it worthwhile and the players would expect to be paid just for appearing.

While prize money wouldn’t be anything like the kind on offer with the Grand Slams and ATP tour, it would need to be attractive enough for semi-retired players to take up their rackets with serious intent again. If we're talking about true legends, then they wouldn't come cheap and the whole tour would have to be structured to the highest standards. One-off tournaments would be a no-no.

The players themselves would struggle to commit to more than a few events, and as such it would be a reasonably short tour, so a difficult decision would be the number of tournaments played and then whether you link the seniors tour to the current Grand Slams or just run independently. Most Slams run a concurrent Veterans section as it is.
