I'm not sure if this is where commish wants these types of suggestions, but here it goes...
I noticed that under the current Constitution we'll use both AVG and H as well as ERA and ER. To me, it just seems a little redundant. A hit already counts towards average, likewise an earned run counts towards earned run average.
Other managers may like having the combos, but I've been mainly a 5x5 or 6x6 fantasy player. I just thought I'd add my two cents.
