T.J. Watt and the Pittsburgh Steelers' contract conundrum is far from simple, with the star aging past his prime.

T.J. Watt has wanted to be a “one-helmet guy” from the second he arrived in Pittsburgh eight years ago.The star outside linebacker took one big step toward that goal on Thursday, agreeing to a new pact that will make him the league's highest-paid defender and keep the perennial All-Pro in black-and gold well into his 30s.

The Pittsburgh Steelers and T.J. Watt have reportedly agreed on a three-year, $123 million extension. With the deal, ESPN's Adam Schefter reported on Thursday that Watt has become the highest-paid non-QB in NFL history for the second time in his career. Watt is reportedly getting $108 million guaranteed.
