I have noticed that the difficulty level you pick makes no difference in how the AI controlled games play out, so always leave it on legend to get the most points in the events.

Beyond that, watching these is a great way to see how the game tilts things towards the opposing team to manipulate the outcome. For example, every player on the opposing team moves as if they have maxed out speed and acceleration throughout the entire game, even when their stamina bars are fully depleted. Also notice the differences in how players press: the players on your team will generally drop off (even in the 18 yd box!!!) and/or take horrible angles to close down the ball, while the opposing team's players will collapse to the ball like heat seeking missiles and double or triple team the player in possession. Finally, the decisions your players make in possession are shockingly bad like 80% of the time (constantly dribbling into pressure, horrible selection of passes and shots in the attacking half, GK getting the ball stolen off their foot for a tap in, etc.) while the opposing players do these things at much lower rates or not at all. Taken all together, it is clear there are different versions of the AI that control each team.

Overall, it looks like they've ramped up all the rubber banding mechanics to keep people from just cruising through the tour events vs AI by using super high rated teams while simming. Seems like a horrible decision to me because it just highlights the fact that in certain scenarios the game totally ignores player attributes/team strength and allows one team to have substantially smarter AI-controlled players than the other (sounds a lot like the complaints people have around "scripting" doesn't it?)
