The Punt Block is dead except the non-punter at the position. If you were poised to nail a vulnerable punter it now has the two defending wing players back pedal and cinch in a barrier block, trapping off the lanes.
FG Block - I used to get the top 4 to race out in a space invaders line towards the kicker and hopefully mess with the frequency; jamming it. Now you don't see that rush coming from the 95 speedsters out in the open.
AI - he has arranged it to cheese ball as much on defense as possible. Cheese ball = you can't get red bars. (i.e. the AI will fling the Man OLB Flat Zone at you a lot....)
FB Dive appearance. You can thank me for it being in the AI's repertoire. LOL
There's other stuff I know when I come across it.
Oh, that conference final/final thing where a dominating GM gets jobbed - I don't think it's in place any more. It got usurped by the trigger mechanisms and traps laid in the current version with how you run your offense. Fall out of line and get zapped. Hence, that 16-0 and JOB code deep in the playoffs is out but the engine is very difficult to navigate on O, overall.
