The Houston Texans have made it look easy so far, opening with two 20-point victories.
The Texans (2-0) will get a more intriguing test this week, when they face old nemesis Peyton Manning in Denver.
It's also a homecoming of sorts for Houston coach Gary Kubiak, who backed up John Elway with the Broncos from 1983-91 and later worked on Denver's staff under Mike Shanahan. Houston lost 24-23 in Denver in 2010, when Tim Tebow was the Broncos' quarterback.
Now it's Manning, who owns a 16-2 record against the Texans from his days with Indianapolis. The four-time MVP didn't face Houston last season, when the Texans' defense made a dramatic improvement under Wade Phillips. Houston held Jacksonville to 117 yards in a 27-7 win on Sunday.
