Good observation, OP. We do seem to get the tip most every time now. Moreover, we seem to score on our first possession more often than not.
Obviously, winning the tip is more than about height, reach and leaping ability. It is more about timing and basketball savvy. KAT has both in spades (not saying that WCS doesn't, of course). Some people just have the knack for it and some done.
KAT also seems to tip it to the same spot every time, and it seems Andrew is right there to get it every time. In a close game, this is one additional possession that could be the difference between winning and losing.
