A lot of what worked for Pop's teams in the past was to have a stopper. In 99, Sean was that guy. The Ninja had just enough athleticism, just enough length, and savvy, to be a pest to all wing players. He did it well enough to win a le in 99. Then the Spurs got Bruce and he filled that role perfectly to the tue of 3 les.
Now, they don't have a guy they can place on an island with the premier scorers or distributors. While Bogans has the want-to, he doesn't have either the length or athleticism. He does fine in stretches, but hasn't yet done it consistently when championship moments are required. RJ has the athleticism, but doesn't yet have the smarts. If only there was a way to combine them.
