Admittedly, I do not understand it that well. I've been going over a lot of game tape but some things do not click. Example, why must PJ be the only ball handler? Why must he drive up the left side? When he passes to Cline why does Cline have to stand there until he gets pressured and then throw it back to PJ? Why can't we throw it to the guy (typically Edwards) running up the middle? Not trolling - asking.
PJ to date turns it over less and I imagine that weighs in Matt's mind. Bringing the ball off center initially allows the right handed player more court AND depending on press or trap...THAT defender is the better "pass interceptor" of the two where the other side is typically the better trapper since most teams are mostly right handed players. I wish Cline would have pushed it across the court quickly since he was not in a position to be trapped and probed the D and then gave it up. I think Purdue would like to get it in the middle.
This is certainly not going to provide an answer you will like, but there are reasons for it. First, there are differences between zone presses and man presses AND how those generalities are attacked. Second, many people are matching up more out of their zones to give a hybrid man/zone similar to a match-up zone typically seen in the half court. Neb played some 1-3-1 trap where they pulled up the middle man higher than a typical 1-3-1 and actually released the middle and right hand side on different possessions to attempt a trap somewhat like a run and jump tweak to the typical 1-3-1.
Some presses are more aggressive than others and more often than not those have a player guarding the triggerman like you might see in a 1-2-1-1 press. Others allow you to get the ball in and try to trap you by bringing two D players into a V at the same time after dribbling. If one comes earlier than the other, the offensive player can get around it. Most people teach to steal passes off the trap rather than be so aggressive with the guy that is trapped trying to steal the ball then and there. if you consider the 1-2-1-1 in comparison to the 1-2-2 or the 2-2-1 you can see that two of those alignment covers the sideline better than others and one covers the middle better than the others requiring maybe a different alignment initially. Remember the sideline is a defensive player.
In the old days with two refs, the rotations allowed were primarily set to see the half court under the basket more on the right side since almost 90% of the initial passes to start an offense take place on the right wing and so the other side of the court covered outside and was the first down the court in transition. This allowed more aggression on the side of the court favored by right handed players. I don't know the rotations as well with three refs, but obviously they can see more areas.
Typically, the man press is more physical and may create more fatigue issues. A pure man is the easiest to break if a team has ONE really good ball player as the others can get far enough away to not allow their man to release and trap and yet still be close enough to receive a pass if their man does release. Generally, less turnovers happen with a man press and of course the end of game situations it allows great pressure and someone close enough to get a quick foul. In a general sense I see the zone press and hybrids more cerebral to attack than the man press and the better press for most situations.
Most presses or traps try to force sideline to use the sideline as a defender. Whether a "pure zone press" or man will "typically" dictate any screening. Depending on the press or trap, teams will try to adjust their personnel to be in the most effective spots and so different teams can do different things to attack or just break a press. Many times you will notice the offensive player in the middle of the court against some zones at least a step back or towards the other team's basket to allow "easier" ball reversal since a "zone press" or even the hybrid "shifts" MORE to ball position than player. Requiring ball reversal eats clock and Purdue does this a lot.
In a "general sense" I'm a believer in placing people in gaps and so I typically prefer an odd front zone to be met with an even front offensive alignment and an even front zone to be met with an odd front offense alignment. That said sooner or later you want to get the ball in the middle of the court whether the first pass across the initial pressure or the second pass...or even the third. Once inside and this is true for just half court sets, looking opposite and being aware of 45 degree angles in passing may provide some good looks.
