I think I'll drop in and give my opinion, but be warned it is no truth, just how I as a manager think it works:
when you loose you best man, and you only have 1 best man and the rest is considerably less good, but all about the same in skills, you might want to turn up the speed. Why? when playing slow you take your time to find your best man to score many points, so when that man is lacking, you might as well play faster because you don't need to find any specific player, they are all equally good and can score the same.
Against a better defense: also turn up the pace. If you go slow, and the other's defense is good (too good for you attack), you'll run out the clock many times and this results in bad quality shots. If you go fast you get more attempts, and at the end of the game you will have more points (even if you shoot the same %, but it is likely your % will be higher as well since you're not struggling against that clock). Note: This has nothing to do with inferior or superior attack of your opponent, I'm just talking about his defense!!
Against his defense: well you will just have to try to put the best possible defense to stop as much points from your opponent as possible, and then hope you did the right thing in your offense and scored more points than your opponent.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
