ALAMEDA -- Assuming the Raiders starting quarterback is Matt McGloin, his first order of business Sunday will be to find No. 99.
For the Houston Texans, it all starts with defensive end J.J. Watt.
Both McGloin and injured starter Terrelle Pryor are familiar with Watt, having faced him in the Big Ten, with McGloin at Penn State, Pryor at Ohio State and Watt at Wisconsin.
"I recall he sacked me in college,'' Pryor said. "I know we had to put double teams on him.''
Watt actually sacked Pryor twice for Wisconsin in a 31-18 win over then No. 1-ranked Ohio State in 2010 in Madison, Wis., with the Buckeyes winning 31-13 the previous season in Columbus.
Sacks and double teams have been a way of life for Watt, the third year defensive end out of Wisconsin who is so dominant his impact evokes comparisons with the likes of Reggie White and Lawrence Taylor.
"He's a great player,'' Raiders tackle Tony Pashos said. "He's as advertised. For such a young guy he's doing a lot of great things in this league. You have to be on your game. You have to be at your best.''
Pashos is on scheduled to start at right tackle, with Watt on the roster as the left end. Defensive coordinator Wade Phillips, however, likes to move Watt to where he can wreak the most havoc, which means he could wind up anywhere along the point of attack.
Considered a preseason contender to be the AFC representative to the Super Bowl, the Titans have lost seven straight after beginning the season 2-0.
The play of the reigning 2012 defensive player of the year, however, has remained constant. Watt has sacks in each of the last four games and 6.5 overall. Last week, in a 27-24 loss to Arizona, Watt had a sack of Carson Palmer which forced a fumble, which he recovered. He also stripped running back Rashad Mendenhall and recovered his fumble.
And that's just another day at the office.
Watt's 20.5 sacks last season led the NFL and was the sixth most since it became an official statistic in 1982. He also deflected or batted down 16 passes, five of which were intercepted by teammates.
At 6-foot-5, 289 pounds, Watt is also a rock against the run, and last season was a part of 95 plays that resulted in zero or negative yards, with 47 of those coming on first down, immediately putting the opponent in a hole in terms of down and distance.
In an era of situation substitution, with defenders who go on and off the field depending on down and distance, Watt is a force on every down.
"I pride myself in being an all-around player, good against the pass and good against the run, a guy you can count on every single play,'' Watt said by conference call.
The scouting report of Raiders coach Dennis Allen reveals no weakness.
"No. 1, he's a big, strong guy that's able to anchor in against the run, but he's got exceptional quickness and exceptional burst,'' Allen said. "For as big as he his, his burst to get to the quarterback is as good as I've seen. He does a good job setting up inside moves and then beating guys outside using his athletic.''
Watt's film work is mostly devoted to what he perceives as deficiencies, a quality that endears him to his coaching staff.
"Everybody looks at the good plays, and those are fun,'' Watt said. "They like to look at the sacks and the batted balls. I watch the plays I can improve on, the plays where I almost got there. It's always the littlest of things -- the littlest hand placement, the littlest foot placement. There are so many little things in the game that can be overlooked but are so crucial."
