My reasons are simple: I'm completely fine with somebody sitting by their computer while watching football all day Sunday - in fact, that sounds fun. To win this game though, I don't want to make anybody feel obligated to do that. It's the weekend - I want people to feel relaxed and not have to worry about missing a key injury because they decided to do other things on a Sunday.
Second, I've always felt that any geographic advantages or disadvantages should be minimized. The most extreme example of this is Yogi - by the time Sunday night or Monday night games are over, Yogi should long be asleep and if something were to happen during the evening games, he would be disadvantaged everytime.
As far as how the new system works, the pool of available players will be available on waivers after the first game on Sunday through Tuesday midnight (for exact times, please see my other post). Players during this time will be added via waiver priority. After Tuesday, the players not picked up through waivers will become free agents and are on a first come-first served basis.
You can still dump your players, but for a short bit of time after the games start, you might have to sit it out and wait a little bit to see if you can add them. After Tuesday though, it's the same as before. In my opinion, JL, this new rule doesn't affect your initial strategy. You can still stream players all you like. You or I (you have to remember that I employ a very similar strategy to you) might not get everyone we want, but that's what the rule is designed to do.
All of this being said, based on past history, my opinion is that this new change will not do much. Players who do research and keep up with sleepers will continue to do so and those who don't won't change either. In any case, I apologize if this new change negatively affects anyone, but I believe it's the right thing to do. All I'm doing is trying limit the amount of time that is almost mandatory that players have to be in front of computers, especially at unreasonable (in my opinion anyway) hours.
