I just try to stay positive as much as I can when I'm losing due to an incompetent partner. I neither criticize nor give advice. I don't feel it's my place to give advice on the court, most of the players have been playing a lot longer than I have. Also, some of the players on my team really don't care how well they do, they are just out there to have a good time. Therefore, they don't really care what I have to say.
I just focus on my game. Perhaps if I join a more competitive team, my views will change. I guess it depends on the company you're in.
