The Byron Nelson football team improved to 2-0 on the season with a 38-13 victory against Frisco on Friday night, and coach Brian Polk said he is feeling better and better about his team as district approaches in two weeks.Nelson will square off with Burleson Centennial on Friday night at Northwest ISD Stadium, and after the Spartans scored 75 points last week, Polk said he knows one thing for sure.“They can definitely score,” Polk said. “I hope they are tired offensively. Good God, they are very, very talented. Up front, they are very big, and they've got a tight end that's very, very talented, two very athletic wideouts and then probably their best player is their running back. They are going to be a test for us defensively.”Polk said he was impressed with his team's effort in its game against Frisco, especially with regard to how the team took care of the ball.“I think we definitely improved from our first game against Timber Creek,” Polk said. “We didn't have all the turnovers. We did have a fumble that we can't afford to keep doing, but we didn't have four, like we had in the first game.“I thought that the kids played hard and we got better, which is pretty much what we preach every week.”Courtney Miles rushed for 175 yards and two touchdowns last week for the Bobcats, and Polk said his contributions cannot be underestimated.“He ran really hard and played really well, and we played really well up front,” Polk said. “Our guys up front did a great job of keeping their players off of him, and when he got out into the open field, our guys did a good job of blocking there.”Polk said he believes the non-district schedule has done a good job of his getting his team ready for district competition due largely to the variety Nelson has encountered.“I think it has prepared us in the sense that we have played some different styles of teams,” Polk said. “Timber Creek is more of pro style, which we will face, and Frisco ran more a Wing T, which we probably won't play again.“Burleson Centennial this week plays a physical brand of football from an offensive standpoint, in that they run it right at you, so I think all of these teams are going to help us.”• For Northwest High School, a trip to Mustang-Panther Stadium presented little trouble last Friday, as the Texans put up 49 points for the second straight week.The 49-10 victory against Grapevine also moved Northwest to 2-0 on the season, as Jesse Drummer threw for five touchdowns in the game.Chase Morrison (five catches, 98 yards) caught two of those touchdown passes, and Dennis Adrole (11 rushes, 77 yards) rushed for two more touchdowns.Northwest will travel to Midlothian on Friday to take on the Panthers at 7:30 p.m.
