I think the line is pretty tight.
Detroit is a bad, bad football team. Game last week vs. the Vikes wasn't as close as score indicates. Lions had a +2 turnover ratio. Peterson fumbled at the 1, (which Vikes turnes into safety), Peterson also fumbled in FG range, and Lions blocked a FG. Last second FG withstanding, and some whacky calls, Vikes should have won about 20-13.
Vikes outyarded Lions 392-212. 180 yards !!
Here's a little nugget. In 5 games Lions have been outyarded by an average of 165 yards per game. At 15-20 yards per point in the NFL, Lions are already 8-10 points down. Lions D is practically dead last in every yardage & category.
Texans outyarded Fish by 115 yards, and only punted ONCE. 4 TOs kept Miami in the game. Earlier post is correct since they have scored 27,27,29 in L3 games. In L2 games at home (Colts & Dolphins), Texans have averaged 438 yds per game. Both defenses are better than Lions statisically.
I'd lean Texans, but personally I am not on them. I just couldn't put my money on the Lions at this moment.
