If you do this long enough we will all have bad partners from time to time. Having said all of that you cannot make use that as an excuse for your ability or the job you do personally. All you really can ever control is your actions. If it was that bad, what did you discuss at halftime or in between quarters? It sounds like to me as if you just worried about everything he was doing and you forgot to do your job. If that is the case, you better improve that soon or people will judge you just as incompetent as your partner is.
It really sounds like to me as if you had no pre-game. I really feel that way if your partner is crossing the lane and not going back. You have to go over something in a pre-game (I do not need your cut and paste Billy
) so that you can at the very least figure out the experience level of your partner and you can figure out before game time what you might have to do.
