No chance, he is falling down going backwards, off balance, only has one hand available to catch the ball, is shielded so he cannot even see the ball. If he caught that it would have been an exceptional to amazing catch. That is not a drop but a good effort by Hill to turn his body around and give himself a chance.
I'll give Hill a pass considering he was considered raw and really wasn't expected by most to start this year, so this season he gets a pass for his play, just like Sanchez got a pass on his piss poor play for 3 years. I won't scape goat a rookie.
