Nothing really strikes me as that unusual about that hand. Im assuming the good player maybe isnt as good as you suspect if he is smooth calling with that hand on the button. On the flop I dont see anything wrong with the button just smooth calling the bad players bet. The pot has probably become big enough where the good player is going to make a play at the pot heads up with this draw agaist a seemingly random hand. Perhaps he was going to wait until the turn and make his decision depending on what fell.

When the straight card hit, I think the action was pretty normal, especially for a game that size. I think the "bad player" three betting on turn is by far the right play.
