I'm a bit skeptical of OP saying this guy is a "good LAG" meaning that I can assume he'll be any good at identifying hero's range. After he as the PFR checks, villain probably expects hero to bet any pair because that's what he would do. If I'm villain, when it folds back round to me I am dropping TT like it's made out of white hot metal, but a LAG may not be.
LAGs can often look great when they are in their wheelhouse, which is sniffing out and capitalizing on weakness. When they are called upon to make a correct technical play, they can suddenly fail surprisingly hard. I liked Case's post as an example of LAG thinking:

"Only half pot, guy's hand is probably not very good, can I bully him?". The idea that a typical LAG thinks "well, a good jack is probably bottom of his range here" is just wrong imo. If he were to consider ranges, he absolutely thinks you can have like 66 here, but a lot of LAGs just don't think in those terms at all.
