I can confirm the lower threshold. I also am doing a cpu vs cpu on NG. I have everything at default and have just been moving Threshold. default (50) I saw more HB TE passes. I am using 35 currently, and am seeing some AMAZING catches and animations by WR's. Short, Medium and even some deep shots. Both for and against me. The other big thing I noticed, (no to get off subject) is the running game. Really amazing the animations I am seeing now.
EDIT: Just to add, I have not done one edit to any players. No rating changes, qb edits or anything. Well except Cap and Gordon. I edit both of them in preseason the first year so they dont show up anywhere.
