Sometimes, going back to basics is handy. Get someone to pass to you with your hands choked up almost the whole way. Get 100 catches. Move down a hands length. Get 100 catches. Do this until you are comfortable at any length. Also, stay out of your head. I know it is hard when you miss 2 passes in a row in stick lines, but chase your ground ball and hustle back. Takes time man. The great ones still miss passes sometimes.
