Maybe, they should both get it: Fed would have 2 more titles but Djoko more finals, more consistency and the #1. I'm sure they could give it as a tie if they wanted to or just give 2 slightly different awards. They simply cannot ignore completely a player who has reached year-end #1 on consecutive seasons for the first time in his career. That would be every kind of wrong.
But as you say, all those discussions may be moot by tonight anyway.
