Plus as a LAG the last thing you want is someone smooth calling with a hand. TAGs will let you know they have something or get out, occasionally even folding the best hand. As Dolye says, they know you're crazy and may be betting an ISD and they don't want to give you free cards. Passives you can end up giving your whole stack thinking "We'll, he can't call on the river with anything less than XXXX, I'm firing this third barrel." And then the guy shows you middle pair.
