This is my first ever fantasy baseball season, so I'm experimenting, but having a solid bat on the bench with multiple position eligibility is quite useful to me. Why? For example, Aviles is 2B, 3B and SS eligible. This is awesome because you no longer need a backup for any of the three positions, and it reduces the amount of "holes" you have on your bench, since you can not have a backup for every single position; having him on your bench reduces the amount of unbacked up players by two. Having backup bats isn't really all that important, since it is pretty much universal that many teams have an off day on either Monday or Thursday, meaning it's highly unlikely your opponent will have an advantage when you have a couple starting positions with players on on off day, and players that are worth their salt will only have a "rest" day once every 2-3 weeks anyway, some even less. Also, if you can use a guy like Prince Fielder who likes to play 162 games a year, might as well grab him, and look at that...another spot on your bench you can use for a pitcher or a backup for an injury risk.
I tend to roll with as many SPs as I can. I currently have seven starters, and zero of them have two starts this week, so having the ability to rotate in extra pitchers allows you to eliminate the advantage of your opponent having two start pitchers, provided he only has enough starters to fill his starting slots.
