Linebacker T.J. Watt has been having a monster season, one many believe should have him as a frontrunner for the AFC Defensive Player of the Year.
He took one step closer to that when he added to his sack total for the season, while at the same time etching his name in the Steelers record book.
Watt, who was tied for the Steelers single season sack record with James Harrison (2008) with 16 sacks going into Sunday's game against the Tennessee Titans, passed Harrison and now holds the team record for most sacks in a season with 17.5.
Watt and Cameron Heyward combined to sack Titans' quarterback Ryan Tannehill in the second quarter against Tennessee, and the half sack moved him into sole possession of the record with 16.5 sacks. He extended it to 17.5 with a solo sack of Tannehill in the third quarter.
Steelers LB T.J. Watt records 1.5 sacks today to reach the most sacks in a single season in Steelers history

"It's a great accomplishment with the historic franchise we have here," said Watt. "There is so much work to do I really can't stop and think about stuff like that.
"It's all about tradition here and to be able to put your footprint in as part of the tradition here is special. I know it's an individual goal. I'm not big on individual achievements. But doing this with such a wonderful group of guys is what it's all about. To be able to be a part of this franchise hopefully for a long time, this is very special. But I really do have more work to do."
Watt has recorded at least half a sack in nine games this season and has seven games with multiple sacks.
Watt currently has 67 career sacks, surpassing Hall of Famer Derrick Thomas (66) for the third-most sacks by a player in his first five seasons since 1982. Only Reggie White (81) and his brother, J.J. Watt (74.5), have more.
"Once you get a sack it's more like a blackout feeling," said Watt. "You do the leg kick and just try to get the crowd as much into it as possible, especially at home. And then you kind of go to the bench and it hits you a little bit like that was cool to have another one. I'm human, I think a little bit about it. But that's not the number one goal. It's more just wanting to be a game wrecker week in and week out and trying to perform the best that I can without putting my other teammates in jeopardy."
