Good call by Tennis Canada I feel, Melbourne is from January 16-29, Montpellier starts January 30, then Davis Cup, then Rotterdam, then Marseille.
The French players will have to make tough calls with their schedules. Will they really want to come back to the west coast after returning to Europe from Melbourne? Will they skip French tournaments and/or the only European 500 in the winter?
Plus with Tsonga, Monfils and Gasquet having spotty injury records, there's a good chance they will not show up with their A-squad.
Meanwhile having the tie in Vancouver will make it easier for Milos to head down to San Jose to defend his title afterwards, and then Memphis where he is defending a final.
Still a formidable task though. Obviously have to make the court as fast as possible.
