The District 7-5A football postseason race remains locked with a four-way tie for second place, and thanks to a 19-7 victory over Midlothian on Thursday, Mansfield is right in the thick of things.The Tigers will travel to Duncanville at 7:30 p.m. Friday, and coach Jeff Hulme said he expects his team to have its hands full.“They are a very explosive team,” Hulme said. “They are going to try to beat you with their athleticism and their speed. They've got great receivers, and I think their quarterback has thrown for 1,700 yards in six games. We're going to be tested there.“They are big on defense, and they're going to get after it. I think we have to do what we do, which is manage the clock and have long drives and be positive on offense, which will keep their offense off the field. Then, like everybody else, we can't make mistakes.”Hulme said the game against Midlothian was a good all-around effort from his team and said he was particularly happy with how the team played defensively.“I was really proud of our team,” Hulme said. “I thought our defense played outstanding again. Our defense has kept us in all of our games so far, and really stepped up again. They had a shut out in the second half, and I think that sort of set the tone.“The offense did enough and made more plays than they did last week, and our kicking game came through with two big field goals and punted the ball well. We were able to correct a lot of mistakes, and I thought we looked better than we did against Timberview.”Nathan McBride had field goals of 26 and 35 yards in the fourth quarter of the game, and running back Julius Lewis rushed for 172 yards and a touchdown in the game.Hulme said the old formula of having a strong defense and good running game has served the Tigers well this season.“That is exactly what I want our teams to be,” Hulme said. “As a former defensive coordinator, I'm going to rely on the defense more than anything else. I am not one of those coaches that puts the best players on offense. I like close games and defensive games, and our 14-7 game against South Grand Prairie is proof of that.“I get real nervous when there are shoot-outs. So I want our defense to play well and I want a strong running game. I think that helps everybody overall.”• Over at Timberview, the Wolves lost to DeSoto 55-20 in a game in which they trailed by eight points heading into the fourth quarter.Timberview actually took a 13-0 lead in the game when Ryan Dean recovered a fumble in the end zone and Nicholas James scored on a 20-yard run.After getting down 28-13 late in the third, Timberview cut their deficit to eight points on a 44-yard touchdown pass from Tevin Muse to Okuzor Radiance.Timberview moved to 5-1 on the season with the loss.
