Years ago I did. Even to put out a quarter season post takes a loooooooong time.
I'd usually do 'pre-season projections and power rankings', Mid-season power rankings, my analysis of the first round of the draft, playoff predictions.
And even that was hard to keep up with for 32 teams.
If you can get one writer for the AL and one for the NL and keep them in sync it becomes manageable because you see the teams in your conference a lot more. Even better if one is 20 mill on college kids and one is 20 mill on HS kids.
