Deshaun Watson is one of the few quarterbacks who can trade points with Patrick Mahomes and the Chiefs' high-powered offense.
The Texans put up 31 points in both meetings against the Chiefs last season. Watson is at his best when the Texans are in comeback mode and not trying to establish their feeble ground attack. They certainly figure to be trailing in this game. 
Kansas City has a strong pass rush, but a very inexperienced and vulnerable secondary. The Chiefs find themselves in this spot because Bashaud Breeland, their most experienced and best cornerback, is suspended for the first four games. 
Here's a telling quote from Chiefs general manager Brett Veach: "With Bashaud Breeland being out four weeks, we're all aware there could be some growing pains and some lumps along the way," he said about his team's secondary. 
The Chiefs have the best attack in football - and are healthy. They are upgraded at tailback, too, with rookie Clyde Edwards-Helaire a starter. Mahomes spearheaded the Chiefs to seven straight touchdowns in Kansas City's 51-31 playoff victory against the Texans. Houston's defense has not improved this season. If anything it has gotten worse.
