Sorry to sound like a dumbass, but wouldn't I need to have an active player in every starting spot, every day to have any shot at winning?
No you don't. Depends on the quality of players on your team and luck. With that said, if a player isn't playing that day, and you have active players on the bench, substitute them out so you don't lose counting stats for that day. That's why you have a bench.
Is it common for managers to leave the same starting pitcher in a starting spot all week and only accumulate stats for him in one game for the whole week?
That depends on your roster slots. If a pitcher isn't pitching that day, substitute him out for one that is if you need the stats. Just remember "P" is an active daily spot on your roster. If a starting pitcher is pitching that day, his stats will count if you're starting him at "P" and not "SP". So yes, you could draft 6 starting pitchers, start them all, and leave them be... but that could also hurt you in ERA/WHIP at the end of the week. It's like having a Monday Night Football game on and you're up by 1 with your kicker left. You might want to bench him because if he shanks enough field goals, you're going to wind up losing and you didn't need his stats to begin with to win.
Yahoo has the set lineup function on your roster page that should make it easier for you. If you've played fantasy football, the same principles apply. If your quarterback is on a bye week, substitute him out for your backup. The only difference is everyday is like a new Sunday. It requires more attention.
