At the 4:01 mark, two things: One good, one bad.
1.) Now that's
an NFL QB footwork! Better than Lienart by far.
2.) He was staring down a covered Jacoby Jones and didn't even look to his left at a wide open KW. Granted, it was man and they brought the blitz, so the pocket collapsed in a hurry, but he never looked left.
a.) I hate it, but it could have very well been one of those "1-read" plays the Texans are so fond of sporting, i.e. AJ wide left and KW in the slot as decoys and you're banking on a favorable matchup one-on-one to the right.
b.) Or...well, he just didn't look left.
