i can't recall the last time i saw a player show such steady incremental progress like this for so many games in a row.
i think the rescue dog analogy holds for this guy. he's not "developing" that much from game to game in the sense of learning new skills between games. he looks to be a much better player steadily emerging from a shell he had been forced into.
he's also either been incredibly lucky or else he is better defensively than he looks to the eye. the botchford gif where he catches up, mistakenly turns and then realized his mistake and then turns again while staying with pearson is an example of the guy apparently being faster than he looks. is he quick enough that he can really do that, or was he lucky and pearson was too tired to walk him?
bottom line: still not enough games to even call him a bottom 6 guy, but if this is smoke and mirrors it will be a great cautionary teaching example along the lines of "before you get too excited, do you remember that time pouliot looked progressively better for <15> consecutive games after we traded for him before it all finally caught up with him?"
otoh, if this is not smoke and mirrors, he is now showing as a potential top 4 guy.
