So you not only need a backup at every position, but one who plays on different days than your starter. Do you figure all that out in your draft preparation? Plus you need to check the lineups for every game, which are not available until about a half hour early, then make the required changes.
JR - that's what makes guys who play lots of positions more valuable. IF they are playing on a Monday or Thursday, you can plug them in at the position you need most.
Obviously, if you check lineups after 6:00 or so on a weekday and see a guy not playing (an x next to the guy, like Grady has right now for today's game) that helps. I know a guy who sets his iPhone to go off at 6:30, then checks.
