College Hoops 2k8 PS3 - why are away games so hard?

[Duke Blue Devils]

Every time I play an away game,I lose. But I dominate at home ( I use duke with 2012 rosters)
Like thispast weekend I played Clemson and I had a 63-53 lead with 6:42 left to go I used Kelly to make a three so it was 66-53 the all of a sudden Andre young makes a three,Plumlee misses a baby hook, they run their offense and cap off 5 more points later on 74-71 I'm still winning, 16.2 seconds left, they run the clock down then Andre young makes a buzzer beater three then it goes to overtime and in overtime, I basically muss almost every shot I throw up while they hit 2 3s and make a bunch of freethrows and eventually win 87-83...

Then I play Maryland at Comcast center and trailed almost the whole game but took a 67-64 lead w/4:06 left then the go crazy bursting out with a 21-7 run to end the game.. But I did a rematch in Cameron Indoor stadium and took a 22-4 lead and they never got any closer than 38-25 in the first half and they never lead. I won 85-58..
Can someone please explain this??(btw I use 20 min. Sliders)
