maybe ... and PROBABLY... but that logic can also be explained away by 2 different examples.
1)
i like to think about when i used to play social basketball - and we had a guy on our team who was a really really bad defender. and he was PF.
So it usually took the opposition teams about 5 mins to work out he was bad defender. So guess what? Their SF would get the ball in the corner and drive or post or do whatever against this guy all game (actually i usually ended up on help defense but anyways)....
Box score in those games would have been PF defended SF 22 times. Could be the game engine does the same?
2) - When i run the stats against a game from last season - where i played 2-3 zone - my PG (starter and bench) defended his SF for all 14 of his shots. Same deal as a box n 1, the offense has simply found a 'chink' in your zone defensive setup and has decided to exploit it continuously. How often this happens though? Not sure.
In your game, probably PF defended SG - MAYBE?
Further to this - As an example of how its never straight forward logic...., i played OB1 earlier this season -
http://www.buzzerbeater.com/match/79205108/boxscore.aspx
His best offensive player was Perez - and he took 40 shots - all of his shots were defended during the game by everyone on my team. PG, SG, PF, C, SF. So this means he shot against the box right?
well i dont know - because EVERYONE on his team, took shots against ALL of my defenders. NOBODY took shots against just one position.
There are no patterns, no logic, each defensive position seems to guard against most if not all defenders. The PF's and SF's guard the least amount of shots, (11) but these are from 4 different offensive positions. The SG's guard the most number of shots, but are still from 3 different offensive positions.
This could mean a myriad of things - it could mean that sometimes the player guarded by the 'and1' gets away from his defender and only takes open shots - or is defended by someone else. It could mean that Patient offense doesn't work the same way with Box defenses. It could mean - well.... anything!
which i guess is my point - one should never assume anything with the box defenses.
