Look, the concern is still there; 2 passes outaide the numbers, one caught, one dropped. Other than that, nothing down the sidelines, nothing outside the numbers. Granted, those routes take time, and this line hasn't given him much. But the Colts were daring him to throw deep, single coverage on the outside; still no shots.
Is it the line & the time? Is it the coaches not making those #1 in progession? Yes, up tempo worked, there were holes in the middle of the field for Boyle, Andrews, Snead, Brown on crossing routes. Yes, those plays eat up game clock, lead to long drives. But sooner or later this offense has to, will need a quick strike, and Lamar seems to be the only qb in the league who can't or won't make those throws.
