They have two great receivers. They have a really good quarterback. They've got a number of good players on defense, and it will be a huge challenge for us.”The Texans defeated Keller by 14 points on Friday in a game where the two teams slugged it out in the fourth quarter, and Patterson said he did not expect anything different.“I thought we played very well,” Patterson said. “I thought they had a really good defense and they did a good job of defending us. I thought our kids did a good job against them. We took a 14-0 lead at halftime and led them 24-0 at one point.“Then in the fourth quarter we both took turns scoring. They never gave up, and they played hard the entire game.”With the second straight victory over an unbeaten team, Patterson said confidence is growing on his team.“There is no question that we are playing with a lot of confidence on both sides of the ball,” Patterson said. “We're doing a lot of good things and getting better. We have a tough part of our schedule coming up with Fossil Ridge, who has one of the most talented teams I have seen in the last couple of years.”Dennis Adrole rushed for 129 yards and a touchdown against Keller.“He has been running real hard,” Patterson said. “He ran really well against Midlothian, and I think it was one of those things where he got into rhythm and ran pretty good.”• Over at Nelson, the Bobcats came up short on Friday night in a 32-22 loss to Wichita Falls Rider.Esteban Ortega actually put Nelson up 7-0 to start the game off on a nine-yard run in the first quarter, but the Bobcats trailed 14-7 at halftime.Ortega tied the game up again on a four-yard run in the third quarter, but Rider answered with a touchdown of its own to regain the lead late in the third quarter.Ortega drew the game even once again early in the fourth on a one-yard run, before Rider scored 10 unanswered points to get the victory.Nelson will play at Lake Dallas at 7 p.m. on Friday.
