I have found that when you start off a bid on a player with something ridiculously low, then more people are likely to bid on them. And when a bidder begins to bid on a player a couple of times, then they are more likely to keep bidding till they get him (since they figure they have already mentally invested a certain amount of money in him, why not go a few bucks more?) The bottom line is if you start a bid on a player at, or close to a reasonable bidding price, say, 40 dollars for Pujols, then you will probably limit the amount of people who engage in bidding.
On the flipside, if you are nominating a player who you don't want, but who you want people to over-bid on, then I would start the nomination off at something grossly cheap.
