David Johnson's second score as a Texans looked easy.
The running back ran to his right on 1st-and-Goal at the Pittsburgh 2-yard line and went in untouched for a touchdown. After Ka'imi Fairbairn's extra point try sailed through, the Texans held a 14-3 lead over the Steelers at Heinz Field, with 11:32 left in the second quarter.
Johnson also became just the seventh running back since 2005 with at least 5,000 scrimmage yards and 50 touchdowns in his first 65 career games. He's the only player since Thurman Thomas to tally 35 rushing scores and 15 touchdown catches in his first six NFL seasons.
His touchdown was the culmination of a 9-play, 54-yard drive that burned 3:58 off the game clock.
On that possession, Watson hit Johnson for a 20-yard completion, and also found Kenny Stills on a 20-yard pass.
At that point in the game, Watson had found five different Texans for a completion of 19 yards or more.
