I just had one of the worst games ever, shooting like 2/20. Fyi, I am generally regarded as one of the best shooters, but I just felt off today and every shot does not feels right. I ever shot 96/100 from the free throw line in practice so its not that I cannot shoot.
You'll get a lot of "do other things", "play D", "get on the glass", type of responses, all of which are true. But they should sorta be true all the time anyway.
But if you're really a shooter, and you're not feeling it, there are a few things that are specifically applicable. First, use your threat. Shot fake every time you catch the ball. If you're uncomfortable enough to question your shot, you should at least be shot faking all the time. If you have the shooter rep, it'll keep defenses running at you, or even better sticking to you. It'll help everyone else. And the real get is to get someone off their feet so you can get by. Draw a foul and get to the line, it's the best way to shake loose your stroke.
The other one is to keep moving. Move without the ball all over. Create passing angles to yourself. That activity, combined with the shot fakes, is often enough to make the only person playing to realize you're in a slump is you.
Get in a rhythem. Be the point and facilitate. Slash to the basket and if you get an open look, take the layup. Otherwise kick the ball out. It gets your confidence up.
Then play lockdown D. I'm taking about quick, shuffle feet, fast hands, and play in the passing lanes. Create fast breaks and be a garbage man. DON'T keep chucking shots unless you get hot. That hurts your team.
OP, my best advice is to keep on shooting even if you've missed your first 6 shots. If shooting is your strength and you decided that tonights not going to be your night, well, you've already admitted defeat.
I find doing shooting motions at every chance is a great tool to get you back on track and also get a feel for the ball/cradle it
