"As for HS and NCAAM, my original statement is correct. You are NOT allowed to bounce the ball across the lane for a throw-in. I don't have this year's NCAA mechanics manual (CCA, or whatever it is); but the Fed Official's Manual says: "All throw-ins on either end line shall be made with the administering official outside the thrower -- between the sideline and the thrower." (paragraph 218) and "When administering throw-ins on the end line and remaining in the front court, handing the ball to the thrower is recommended." (paragraph 220)."

Not to play the devil's advocate or throw unnecessary fuel on the fire, but the rule doesn't state that the preferred position is between the nearer sideline and the thrower; and a position "outside the thrower" could easily be interpreted as being certain that the thrower is bracketed by the lead and trail officials. In my opinion the positioning requirements should be more explicitly stated.
