We were able to get some experience doing that last year

Said Kelly: “We were able to get some experience doing that last year during the preseason, but now doing it in a regular season game — that’ll be the first time.”

While the Texans get ready for the regular season, Kelly will also be taking a look at the strengths and weaknesses of the Chiefs’ defense and figuring out how to create the best matchups for quarterback Deshaun Watson to exploit.

“Knowing the roster, it’s good to be able to know what the strengths and weaknesses are of the different players so you can take advantage of what they do well, try to capitalize on their strengths and the different matchup issues that they may present,” said Kelly.

Kelly will be the second offensive play-caller in the O’Brien era. Offensive coordinator George Godsey took over play-calling when he was the offensive coordinator from 2015-16.
