Seems to me there is a lot of hyperbole in there. You simply can't put him up there with the best players in this league and you'd be mistaken to think there aren't many of those that work just as hard as Gilberto does.
Bad offence or not the guy squandered a fair number of chances. First touch was also not very consistent. At best he's in the Claudio Bieler, Kenny Cooper, Eddie Johnson category until he proves otherwise.
