I don't think Hedo become an starter to boost his confidence. At the time, he had better numbers than Manu but Manu proved to be better.
Now, it you people think that an NBA player needs to become an starter to have confidence....you are wrong!!! These are professional players for god's sake!!! Stop babysitting them! They win millions playing in what they like, so if they want confidence and respect, EARN IT!! Look at rose, last year he almost didn't play. And Devin won his minutes, so don't give a prize to whom doesn't deserves it. End of story
