See how star Chiefs QB Patrick Mahomes reacted when news broke that Kansas City's front office had extended veteran OL Trey Smith.

The contract reportedly includes $70 million guaranteed, and will make the 26-year-old the highest average salary of any player at his position in the NFL at $23.5 million annually.

Smith's new deal, at $23 million per year, also guarantees the offensive lineman $70 million. The 26-year-old Smith becomes the highest-paid guard in NFL history, topping Philadelphia's Landon Dickerson, who was extended last year at four years and $84 million on a contract with a $21 million average annual value.
