Hindsight confirms what some of us have said from the time Splitter was drafted. He makes the team better on both ends, particularly on defense, and particularly because of the pressure he takes off Duncan. He would have been better to have on the floor from the day he arrived in town. Period. There's no way to distort that. People talking about space seem to think that offensive spacing matters when you have two bigs that play the pick and roll as well as they do. It doesn't. They aren't competing for post space or both standing 15 feet away shooting jumpers. I predicted the Spurs' pick and rolls would become unlike anything we'd ever seen when Splitter was on the floor with Duncan and Manu and Parker. That's what happened. Instead we had a year that he sat on the bench and they decided to mess with his shooting form, which wrecked his free throw shooting for over a year. Wasn't well handled. I'm just grateful that they finally figured it out.
Scola was a power forward When Scola was traded, Duncan had played his entire career at power forward next to true centers. There was a case to be made, since he and Duncan played the same position, though Scola's jumper was far more reliable than anyone was saying at the time, and he would have been a quality addition to any team.
Splitter is a center. Always has been. It's why they play well together.
