I get the sentiment for having a positive, celebratory period. After a win, there is a desire to bask in that glow for a bit.
To bolster this position, I feel Sag made a very astute point. There is a time and place for everything. And right now, the Rams are in a happy place of being proud of a hard fought win. Critiquing comes later.
OTOH, I agree with Jemach. Critiquing is fun. Personally as a future oriented person, I'm always up for discussing how something could be better. It's why I can talk next year's draft at any time.
But critiquing has its downsides too. A couple of weeks ago, I was a little irked with what I felt was negativity after a win. In hindsight, I realized it wasn't so much that there was a strong tone of negativity, it was that I saw two critiquing threads before I had a chance to see the game for myself. So I started off in a bit of a sour place. That's my fault. I could have chosen to see the game, form my own opinions, and then visit the critiquing thread.
Ultimately I think I fall on the free expression side of things. I've noticed that we tend to get more board participation on negative, critiquing type topics than positive, celebratory ones. I'm for whatever gets the most board participation because that's why we all come here.
