So.. what's changed?

Whats been improved for scouting? Is it all AI/behind the scenes stuff? How does the recruiting money available effect our scouting and recruiting points? Better coaches may cost more money (taking less from recruiting) but they should be able to recruit better players, yes?
Weather effects? There's absolutely no information about the weather on the Matchup screen nor when you go to play the game. That makes no sense if we don't know what to expect in this game. If its going to rain/snow surely you want to run the ball more. If its a windy game maybe we'll stick with shorter passing routes. Without knowing the weather going into the game how do we prepare for it?
Player ratings/personalities changes? What happened here?
Also, "Add walkon" doesn't seem to work. Is there a specific time we can use that feature?
