I believe the late great Jeffrey Pressman most loudly celebrated the tier notion - here's a collection of players all about the same value. I will not bid early on those in this pool of talent, hoping to get a bargain when the bin is almost empty. But then one may end up in a bidding war with someone playing the same strategy, when only one player in a particular tier is left and the tier below is garbage.
Deep thoughts, right?
