If you've noticed that the 2 to your left haven't been defending their blinds, then that's a good situation for you.. plus it's cheap cuz if they're tight you know they'll probably call you with good values, and check the flop if they miss.. position is good even if you have nothing on tight players

more aggro players and people re-raising your 'projected' steals (you prolly have legit hands sometimes) aren't good.. also lots of people are tight, but like to defend their blinds as part of a balanced strategy and for pot odds
