Agree to that, even you point your finger to who you think should held responsible to the loss there's nothing that can do about the outcome, better to accept the result and move forward, that's also how important the budget amount that you use for your gambling, amount that you can let go to avoid being aggressive and chase for your losses. We don't have the control of certain situation even how good both the coach and the players if the plan did not work according to the expectation then upset may happen.
Even if the team does not show the result we expected, we should perceive it as a statistical error. Because we will make many more bets, based on the results of which we will find out our result, whether it was positive or not. In any case, we need to understand that the casino or betting platform will always be in the black, because they have already calculated what is profitable for them on the odds. That is, even if we guess well, we must remember that it makes good sense to also choose the best odds among those offered to us by other betting platforms. In short, I do not completely ignore the guilt of the team, but look for it only in myself or the incorrectness of my betting strategy.
