Stats wise: 2003-2004 - 1.9 steals, 2.8 blocks; 2004-2005 -- 1.6 steals, 3.3 blocks; 2005-2006 - 1.5 steals, 3.2 blocks. And remember he was playing the forward position so you don't get as many opportunities for blocks as a center. Can you name any other small forwards, even power forwards who led the league in blocks? AK was a supreme shot blocker. But like one poster suggested, just imagine putting AK in his prime on this team with Rudy. Definitely would be challenging for the finals. He was also one of the most adept at picking the pocket of a dribbler if you might recall. His one flaw was he depended too much on his athleticism rather than positioning when defending, which used to drive Jerry nuts. But that was something he could've corrected.
If he had just concentrated on defending instead of worrying about his touches, he could've been the greatest defensive player since Bill Russell -- who was without question the greatest defensive player in NBA history.
Of course, the bias on this site for how AK ended up clouds their vision of what he was like during his best years and before his injuries. Remember he was All-Defense First Team multiple times, and I think one year, runner-up, when he probably should've won it.
