Blake Griffin, DeMarcus Cousins and Finishing the Play (Blake vs. DMC part two)

However, while Cousins is better in an offense initiation role due to his ability to draw help and distort the defense's shape, he doesn't necessarily rise to the level of good enough to want that to be your primary option. Post scoring is not particularly efficient, averaging about .82 PPP leaguewide vs. .91 for all possessions. It's also harder to get post shots in late game situations both because of the extra physical leeway defenders tend to get both before and after the catch in crunch time, and because it's difficult to run a post play which gets a shot off at the appropriate time. (This last is a major if not THE major reason why quarter and game ending shots are so difficult. The element of surprise is removed to a degree as the defense has a great idea when the shot is occurring which allows far more focus on who is going to take it and pressure on the area of the floor where it is likely to occur. But I digress). So for a team with real ambitions, these two players (since Griffin is a worse post player to begin with) are probably best off as secondary, finishing options rather than primary/initiating options.
Certainly in transition, Blake is one of the more efficient (as well as most spectacular) players in the league, as well as being a good passer. Cousins, though an underrated and surprisingly fast player in transition, often makes the mistake of believing that because he CAN handle the ball and lead the fast break, he should do so - he turns the ball more than one out of every 5 transition possessions so far this season. (This may be an early season aberration as it is a significantly higher rate than last year.)
Griffin's advantages as a play finisher can be seen in his success as a pick-and-roll player. His combination of strength, agility and explosiveness make him a great foil for Chris Paul in the Clips middle PnR game. He isn't the most efficient player in the league as a roll man (currently 28th per Synergy) but he's well above average while finishing more plays as a PnR roll man than anyone else in the league - without doing the heavy lifting, his net "Points Above Replacement Play" as a roll man have to be among the highest of any single player and shot type in the league. Since pick-and-rolling is in general a more efficient play than a post up, Blake's primary offensive weapon is almost 12 pts/100 more effective than Cousins postups.
And if anything, those numbers understate his effectiveness given his ability to catch the ball on the move and make a quality pass:
Blake's mobility also let's him run continuous PnR's from opposite sides of the floor, which can break down even the best defenses:
Even with the skewed reward system, at the end of the day an open shot is [usually] more efficient than a contested one.
But basketball is a living and breathing organism, and offenses and defenses are in a constant flux of adaptation and reaction. The long 2PA is a bad shot because of the math, but also because there aren't many great long 2PA shooters in the league (the lost art of the midrange).
Even with the skewed reward system, at the end of the day an open shot is (usually) more efficient than a contested one. As such, it stands to reason that as more and more teams adopt the type of defensive principles practiced by the Pacers and Bulls, the greater the need for players who are able to exploit the inherent weakness in the system: the midrange jumper.
