Stop yelling at your teammates! Do you find yourself yelling at your teammates in game? Does it work? Does it bring results? To be fair I've yelled at my teammates during a game or practice and I've been yelled at as well.
Teammates yelling at each other during games seems quite common. See Draymond Green! He loves a good yell! Why do we shout at our teammates though? What does it say about the person screaming? Is it a good motivator? Here's what I've observed over the years from other teammates and why I've personally yelled at some players.
Top reasons in no particular order for teammates shouting at each other:
Missing easy layups
Screwing up plays constantly
Rarely helps/rotates on defense
Overall sucking at defense
Not playing how others "think" they should play
Let's address them one by one.
Missing easy layups
Yeah definitely teammates will get annoyed with this. As to why people might miss easy layups, maybe they are too amped up or nervous or they just lost their balance due to a shitty court. If they are nervous, then especially yelling at them most likely will make the situation worse. Yelling at someone who's nervous will probably make them more nervous.
Screwing up plays constantly
This could just come down to not practicing them enough or nervousness again. Same thing, yelling probably won't achieve the result you want, it'll probably make it worse.
Rarely helps/rotates on defense
The player is either a bit lazy that day or they don't know how to properly play help defense. So yelling is a hit or miss here.
Overall sucking at defense
They could be just not that athletic or laterally quick enough to play good defense or they don't know good defensive strategy. Yelling will fail here if that's the case.
Not playing how others "think" they should play
Players might approach the same situations differently or two players are just not at the same levels. If one player is a division two player and the other is fresh out of high school, there might be some friction between the two due to experience levels. Yelling probably won't work in this situation.
Why yelling doesn't work
Why yelling doesn't work most of the times in the above situations is because the player being yelled at is probably doing their best, trying their hardest. If you shout at a player and that player internally believes they are trying their best, you're going to have problems. That player will probably try to tune you out or push back which can lead shouting matches or worse.
For example, if you see that your teammate is getting blown by every defensive possession, most likely they are laterally slow and you can't magically make them more athletic at the moment. So you need to lower your expectations.
If your teammate misses easy layups, yelling at them most likely will help them to miss even more.
So what to do?
My advice is to try to talk to them one on one in a calm manner. You can try and do this on dead ball situations or during end of quarters/halftimes. As well, you can try and save your advice for after the game and try to figure out what's going on with the player. Be respectful when you speak to them. You need to focus on keeping yourself calm also, this can be achieved by trying to keep your expectations of the player in check. Are your expectations too high?
But... maybe there is one good time to raise your voice...
There is a specific situation where maybe it is good to shout at your teammate but there is a risk in doing so. If during the game you see one of your teammates being a bit lazy and you know them well and how they play, maybe this is a good time to try to "wake" them up and get their adrenalin going. But like I said this could be a risk. Your teammate that you know very well could be having life issues, or your assessment of their effort could be wrong since you are also playing and not watching them play 100% of the time so be careful with this tactic.
Overall I think when a player is shouting at another player, it displays a form of panic. The player yelling is most likely panicking at that moment. Leaders need to stay calm and minimize that look. Panicking doesn't invite respect, nor does sulking. If you want your teammates to perform better, talk to them respectfully, don't look to Euro League coaches as something to emulate.
