Chiefs sign Mahomes

The Kansas City Chiefs signed their first-round draft pick, quarterback Patrick Mahomes II of Texas Tech, on Thursday. Mahomes, who got the rookie standard four-year deal, is expected to back up incumbent Alex Smith as a rookie this season. Smith is playing out the final year of his contract, and the Chiefs aren’t expected to re-sign him for 2018. Kansas City traded up from the 27th pick in April’s NFL Draft to acquire Mahomes with the 10th overall selection. It had been 34 years since the Chiefs took a quarterback in the first round, when they took Todd Blackledge in 1983.
