Bruce Arians, who coached Tom Brady to his final Super Bowl victory with a dominant win over the Kansas City Chiefs and Patrick Mahomes, recently told Peter King of NBC Sports why he was unable to draft the three-time champion.

Arians, 71, was the head coach of the Arizona Cardinals back in 2017 when Mahomes went to the Cheifs. Andy Reid moved up to select him with the 10th pick.

The Cardinals had the 13th overall selection and Arians admitted he was stunned when Kansas City stole Mahomes from right under their noses.

“I was stunned,” Arians said. “I figured (the Chiefs) were a playoff team with a good quarterback in Alex Smith. I thought Pat was gonna fall to us.”

Sean Payton also wanted Patrick Mahomes

Former New Orleans Saints head coach Sean Payton also wanted to draft Mahomes with the 11th pick, but settled for Marshon Lattimore.

“We really like this Patrick Mahomes kid,” Payton said inside the Saints’ draft room, per King. “He’s the steal of the draft. I’m not sure everyone knows that.”

Reid did well by moving up to 10th to draft Mahomes because he would have definitely been gone by the 27th pick, which was were the Chiefs were before trading draft capital to the Buffalo Bills.
