Yeah, I was talking about them starting together at some point. It's not going to happen but it seems to make too much sense for it not to.
Another thing I noticed, Splitter as the roll man creates just as many 3-point opportunities and plenty of enough spacing on the floor, especially when paired with 'Dyess. The difference is, you get more 3-point shots from your backcourt and at the wing instead of at the 4 -- defenses actually having to collapse on Splitter because of his size, mobility and the away he attacks the seam or slips to the basket without hesitation.
When Duncan's that roll man, teams can usually live with that. So long as they're not giving him a dunk or layup unimpeded, Tim's not what he once was on the roll. When it's Blair, teams tend to have a decent amount of success given his size (or lack thereof). 'Dyess isn't one to complete many a roll in traffic on the move (sans a straight-line drive to catch and score at the rim) and Bonner's camping out at the 3-point line; both 'Dyess and Bonner are pick-and-pop players, not roll.
What I'm getting at is, defenses are forced to honor and pay attention to Splitter differently than any of their other complimentary bigs and the way they play him creates similar opportunities, just from a different position or spot on the floor.
