I am still somewhat new at this and don't quite get it, but right now through 9 games I am 5-4 with a 38 rpi. By far my most promising start that I have had (i think this is my 4th season). Anyway I am coming across a strange trend in my games. Through the 9 games, I am a combined -63 in the first half, and +58 in the second half. I play man to man and triangle, my stamina's are incredibly average, and I either play slow down or normal pace. I am having an extremely difficult time trying to make sense of this pattern, any attempted insight would be appreciated.

Well, it does seem like you are rather consistently getting opponents starters in foul trouble, that coudl contribute ...

Some additional thoughts.
- Small sample variance
- Is the sim adjusting your defensive balance at half time?  If it does and it results in a better 2nd half- it MAY mean (sample size warning again) that you could have game planned better by starting with that balance instead. 

Thanks for the different viewpoints. I went through each game and I think rust is right on one point, I need to see more games to be able to figure this out. In some games I do get people in some major foul trouble, but in some I don't. In quite a few games my original game plan seemed to be on the right track, but at half time it is tweaked even father than I had it (-1 to -3, -2 to -4). But there are also games it was only tweaked by 1, or none at all. I think my team is just hungover for the first half and snap back to life after they have some of Michael's Special Stuff during half time.
