ENGLEWOOD, Colo. (AP) — Peyton Manning was disgusted with the Denver Broncos offense after the first of three practices with the Houston Texans.

And when the five-time MVP isn’t happy, nobody’s happy.

Asked specifically what had set him off, Manning stared at a reporter like he had stared down receiver Bubba Caldwell after a poorly run route or two an hour earlier.

“Were you watching?” Manning retorted.

What observers saw, actually, was a Broncos offense that produced its share of big plays in both 7-on-7 and team drills against a defense led by J.J. Watt and Jadeveon Clowney. But also some sloppy moments less than 48 hours after a chest-thumping 34-0 shutout of the San Francisco 49ers.
