Probably the same point Steve Bruce had when he wanted to flog him to Boro the year before we sold him to Leicester, that people at the time didn't think he'd make the step up to the PL (and it wasn't an unpopular opinion at the time)
Like I said, I wasn't sure if his point was supporting yours or debating it, as a lot like to jump on the Maguire hate bandwagon these days.
