The AFC South side's defense managed to sack Falcons quarterback Matt Ryan five times during the 27-16 win.
The head coach told reporters: "Obviously, a great team win for us in the pre-season, it is always nice to win no matter when it is. We came out against a good football team and I thought the defense early [they] got some yards, but we held them to field goals, field goal tries.
"We did a great job on third downs which allowed the offense, we had a little slow start the first couple of series with the turnover. Then all of sudden we did a great job and it is 7-6. We are in the game and we have momentum.
"So, a lot of good things there to finish the game in the four-minute which was good also. A lot of things we hadn't been as consistent with in the first couple of weeks all came together tonight, so that was good to see."
The Titans finish their pre-season against the Minnesota Vikings on Thursday.
