[Chimera]

I don't want to put words in Leavenfish's mouth, but I take the quote to mean that if there's a preflop raise, it creates a larger pot, which makes people more inclined to stay in with marginal hands (like middle or bottom pair), especially since they don't realize they're up against a set (and thus drawing very thin). In other words, they're getting good pot odds, regardless of who put the money in the pot.
