NORMAN, Okla. | Having to think about which team has the edge in the passing attack and on defense is the strongest indication today&#8217;s Texas Tech at Oklahoma game should be off-the-charts good.</p><p>Bob Stoops&#8217; Sooners not the dominant defenders? The teams are nearly dead even on average points and yards allowed.</p><p>Mike Leach&#8217;s Red Raiders not the easy call for air supremacy? Oklahoma ranks second to Tech in passing yards, and Sooners quarterback Sam Bradford has more touchdown passes than counterpart Graham Harrell.</p><p>Tech-Oklahoma seems to be that even entering tonight&#8217;s titanic matchup, which will either provide clarity or more confusion to the national championship picture and Heisman Trophy competition.</p><p>With a victory, Tech clinches its first appearance in the Big 12 Conference championship game and would be a triumph over Baylor next weekend from an outright South division title.</p><p>The Red Raiders would strengthen their grip on the No. 2 ranking and begin to think about booking nonrefundable flights to Miami for the BCS title game.</p><p>An Oklahoma victory muddies the water by forcing a three-way tie atop the South. The Sooners, Tech and Texas would stand at 6-1, and if they all win their regular-season finales the following week, the representative in the Big 12 title game would be the highest ranked of the three in the BCS standings.</p><p>Victory may take a Heisman Trophy effort, and nobody has the edge there.</p><p>Harrell leads the nation in passing yards with 4,077, and Leach said he&#8217;s the best in the conga line of Tech passing artists who have ranked at the top or near the top nationally in passing statistics the last several years.</p><p>&#8220;He looks as efficient as any, or more efficient than any of them,&#8221; Stoops said.</p><p>But Stoops likes his own guy. Bradford leads the country in touchdowns with 39 and the conference in passer rating.</p><p>&#8220;I&#8217;ve got to say that Sam Bradford, for everything we ask him to do, for me, is clearly above everybody else,&#8221; Stoops said.</p><p>There are differences between the quarterbacks and their schemes.</p><p>Tech primarily uses slants and screens and rolls up huge numbers in yards after the catch. Wide receiver Michael Crabtree is the favorite target and big-time playmaker. He has 18 touchdowns this year, has averaged 7.8 receptions per game and turned in the season&#8217;s highlight moment when he turned a fade route into a 28-yard touchdown reception with 1 second remaining, giving the Red Raiders a profile-boosting 39-33 victory over then-No. 1 Texas.</p><p>Bradford tends to look downfield more and averages an amazing 10.32 yards per attempt, which means the Sooners average a first down every time the ball leaves his hand.</p><p>One edge Harrell has over Bradford is experience in this game. This is Harrell&#8217;s third start against the Sooners, and Tech won last year&#8217;s game in Lubbock 34-27.</p><p>Bradford started the game but was knocked out after suffering a concussion on the Sooners&#8217; first series.</p><p>&#8220;I&#8217;ve watched it, so I pretty much know everything that happened,&#8221; Bradford said. &#8220;Let&#8217;s hope it doesn&#8217;t happen again.&#8221;</p><p>What has made both quarterbacks&#8217; jobs easier is the supporting cast. At Oklahoma, a strong offensive line, potent running game and a defense that allows the Sooners to often dictate the game&#8217;s pace has been a given under Stoops.</p><p>Having those qualities come together at Tech this season is a first for Leach. Amazingly, in 499 pass attempts this season, the Red Raiders have taken a mere five sacks and Harrell has thrown only six interceptions.
