Needing serious help on not getting blown out in 2nd half

[TheLegend5]

I am constantly getting blown out in the second half. Not just like every now and then, but almost every game. I'll even play the same game 5 times and the same thing continues to happen. I am within 5 or even leading by up to ten and then by game end, I've lost by 20.

They shoot above 60% from the field, and I shoot below 40%. They out rebound me, I turn the ball over 8-12 times in the second half, when it was 2-4 in the first half.

You can even feel it coming. I start missing layups constantly with little contact, I throw the ball into the stands to wide open guys on the wings, and even on 2 on 1 fast breaks. Defenders start to not find their opponent.

Does anybody have any kind of half time adjustments to make? I mean some times teams just go down the toilet, but 85% of the time I play it is happening after playing a really well and competitive first half. Starting to get frustrated and was hoping for some help on how to tweak my team when this starts to happen.
