I watched all the Packer preseason games and read more articles/tweets than I care to admit in order to follow Williams and Hill (and for a little bit Pearson)

Hill beat out Callahan clearly. He outplayed him by a long shot. Packers took a risk by only having 2 quarterbacks on their 53 man roster and obviously, now they regret it.  Hill had a couple impressive runs as you'd expect but, he threw the ball very, very well and made all the right reads.  IMO, if Hill were still on that PS, Hill, not Callahan gets the call-up. Thats my opinion being as objective as I can.
