I'm pointing out that Duncan, in his prime, and DROB, even in his twilight years, was still a great athlete, and a dominant defender. Not sure that Duncan and Splitter can be as effective as the Spur's original twin towers. Part of that reason is the evolution of small ball, that alot of teams use. Now if teams employ traditional lineups, for ex., the Lakers, I'm almost positive that Duncan and Splitter can matchup effectively against them, but OTOH, teams like the Sixers, who throw out smallball lineups, are a cause of concern for me, just because we haven't seen alot of Duncan and Splitter on the floor together guarding small ball lineups. Which the reason I started this thread.
