Stop me if you've witnessed this before - Kelly Olynyk, a great three-point shooter whenever his shoulder is cooperating, one step behind the three-point line, wide open.
Instead of shooting the open three he puts the ball down on the parquet floor, dribbles into the lane past a switching defender and either passes the ball or goes for a layup.
As Celtics fans we've seen this time and time again. Olynyk has been a constant headache for Celtics fans who wish he would be less of a rim attacker and a more willing long-range shooter.
But as it turns out, maybe those fans shouldn't be too upset.
