Assisting has changed? To me, this awfully seems like you just trying to avoid the question for the sake of convenience, but whatever. This question conveniently become difficuly for me to answer if we ignore past eras, seeing as there are very very few dominate-centers in today's NBA, that command a similar amount of possessions to Al Jefferson. From what I can think of, I'd guess that Bogut and Howard both get a similar amount of possessions per game. Bogut averages 2.6APG, 0.4 more than Al. Dwight, on the other hand, averaged 1.9, despite the fact that his team was packed with much more capable shooters than Al Jefferson last season. So should we really be expecting our 5 to me averaging THAT many more assists? Unless we stumble across a career 3.1-3.2 APG 4/5 like Pau or Duncan, we cant really do much better than Al, but we sure could do a helluva lot worse.
