The St. Louis Rams, Detroit Lions and Houston Texans are the three remaining undefeated teams and all three would like to keep their record unblemished and head in to the regular season on a high note. While preseason football doesn't count for anything on their record, it does give the team more confidence if they perform well.
The Rams play the Jaguars in Jacksonville and they should have plenty of opportunities to beat the Jags. Look for Sam Bradford to have a big game against a rather porous Jaguars defense. The Rams have a favorable matchup and should end the preseason undefeated.
The Lions play the Bills in Buffalo and play a Bills team coming off a win against the Jaguars. The Lions have the best point differentials so far and that shouldn't change after this game. Look for the Lions to keep their undefeated mark.
The Houston Texans play the Vikings in Minnesota and it should be an entertaining game. The Texans dynamic offense will matchup with a good Vikings defense and something is going to have to give. The Texans are the team most likely to lost their perfect record but I think they hold on to become the third perfect preseason team.
