Defending your BB in Limit

[Net Warrior]

Here's the thinking I find useful:

"Still another great player says he’ll usually defend with anything, even 3-2 offsuit. Good players do this because the pot is laying them 3.5-1 immediately (the raise is two small bets, the small blind and big blind total one and a half small bets, and it costs one small bet to call), and furthermore, the late-position player is going to bet the flop after the big blind checks nearly 100 percent of the time. So, in a way, we’re really getting 4.5-1 to call the raise."

Looking at it this was it's easy to see the pot odds and which hands are worth defending. I don't think 32o qualifies but 97s which I would have folded in the past seems playable to me now for example.
