The Spurs could accomplish this trade without Splitter's inclusion, that point has already been discussed in another thread. Utah doesn't need another big, that's the reason they're shopping Jefferson now. As to whether his presence would bring a championship to San Antonio --- damn sure wouldn't hurt. IMHO!
I'm great at multi-tasking -- I can waste time, be unproductive, and procrastinate all at once. Ain't life grand!!
