A major problem for the C's last year was there 4th qtr offense. They struggled to start qtrs and had to fight all qtr long to either get back into a game or hold a lead.
Here is where Shaq steps in. Shaq for his diminished game can still do one thing well, back down an opposing player and draw a foul. Even if he only makes 50%, it will be good for the bigger picture. More fouls early mean more free throws later. These free throws will be for Allen, Pierce and KG. All very good, if not excellent, free throw shooters.
We all saw how getting to the line in the 4th can win you a championship. Having that ability now on the C's side will have a dramatic effect on the C's ability to score points at the end of games.
