Five nuggets of knowledge about Week 4:
Containing Kampman: I believe the Colts loved what they got from offensive tackle Jeff Linkenbach in Denver last week. But I am not sure if they are ready to go with an undrafted rookie against crafty and explosive veteran defensive end Aaron Kampman or if they want to get Charlie Johnson (foot) back in the lineup to deal with Kampman. If it’s Johnson, we know they are bringing the rookie along slowly and allowing Johnson more time to heal. If it’s Linkenbach, it says they love him and he’s better than a banged-up Johnson, or has better upside than Johnson, or both.
Deep speed: Titans cornerback Alterraun Verner had a wonderful training camp and preseason, making a ton of plays. The question about him is his deep speed. And so I’d expect the Broncos to work quickly to test his deep speed in his first start in place of Jason McCourty, and to find out how well Verner and the Titans’ scheme can cover for it. The Titans are one corner injury from trouble now. The next guy up, Ryan Mouton, struggled as a rookie in 2009 and watched McCourty and Verner sprint past him in the preseason when the open job was supposed to be a three-way battle.
Survivable: The Texans aren’t getting sufficient pass rush and their defensive backfield isn’t making plays. They shouldn’t be relaxing because Bruce Gradkowski isn’t Peyton Manning, Donovan McNabb or Tony Romo. But you’d think they’d be able to survive their deficiencies a bit better against Oakland than against their three previous opponents. If Troy Nolan can make the most of his work at free safety -- he and Dominique Barber are expected to split time -- he could stake a claim to the fulltime job.
Back or benched? Jaguars cornerback Derek Cox lost the team’s faith after what the coaches lauded as a great rookie season. Surely they can play better pass defense against Manning with Cox involved than without him. Cox picked off Manning to end the Colts’ first drive in the season opener in Indy last year. Jacksonville has the sort of secondary issues that would suggest a quarterback who has been practically perfect so far can carve things up.
Quick out of the gate: The Texans' defense has played OK in the first quarter, and then far worse after that, according to Aaron Schatz and Football Outsiders. To give the defense the best chance, a hot start by the offense would really be big. Get Matt Schaub in a rhythm, get Arian Foster going and get multiple scores on the board and the Raiders will have to chuck it. Given that scenario, Houston could pick off its first pass of the season just by accident.
