Although it is still technically Monday, you can pick today if you know what you want in round 1. It is due by end of day (eastern time) on Tuesday.
Round 1 = you get two players from your main franchise. (due by Tues)
Round 2 and later = one player from the next franchise. (due by Wed, etc)
You can submit your stadium with round 24, but it needs to be one used by your franchise since 1969. Not much to pick from!
I don't care if people pick early (so long as all prior picks for that franchise are in), but you absolutely need to name the round and the franchise with each pick to avoid confusion. So if you WANT to do your round 1 pick tonight, feel free. Not due until Tuesday.
Example: "r2 padres Clay Kirby"
