I just watched the INT 10 times in row, and I'm behind the action, but that's an atrocious play by Alshon. He had a slow get off, poor juke off the line, didn't get the edge for the outside fade, and made zero effort after the DB contacted him.
Not a great throw by Cutler - it should have been further into the corner - but it would be nice if Alshon looked remotely good on that play.
Having said all that, I hate the Bears' play-calling in the red zone this year.
