I've got a few players who are currently having confidence problems. They've either had a run of bad luck, or made a few bad plays in a row and suddenly it gets in their heads. I'm trying to decide the best way to handle the situation. It's likely different for every player, but the way I see it you've got two basic ways to handle the situation. You can keep putting them in tough situations, situations they are currently having problems with, to show them that you have faith in them. Or, you can put them in situations they are more comfortable with and allow their confidence to return before putting them back in a situation they are having problems with.
I remember several years ago in summer league, I had back to back games where I had a key turnover late in the game. It got in my head so much that I didn't even want to be on the field. My captain at the time took me aside and told very nicely to get over it, that the team was going to need me playing to succeed, etc. It encouraged me to get back on the 'horse', and eventually I regained my confidence. I think an important part of it was that someone I respected showed they had confidence in me.
Does anyone else have any experiences with players (or yourself) having confidence issues?
