Ejim was not that great a 3-point shooter. It's Kane's overall dynamic and his 3-point shooting that hasn't been replaced. Big, strong, powerful guard who had a pretty good year shooting the ball.
In regards to Ejim, what hasn't been replaced is his rebounding. He was a force to be reckoned with on the glass because he was just athletic enough and had a really strong body. This team sorely misses that.
