im just like you guys, but my favorite day is the day after the regular season - or a bit earlier if i end with byes - when i can finally put in a winning-based lineup, instead of a growth/promises one. growth continues now which i don't love, but i feel like the balance still tips at that point and its go time! that is definitely my favorite day, when the post season is still filled with possibilities, no reality to rain on that parade yet.
i also get really into that first day sometimes, depends on the team - for the good ones i am always dying to see the off season improvement.
