Sloter and his family watched all three days of the NFL Draft in his hometown of Atlanta to see the quarterback market take shape. He knew Saturday morning that he'd have a team later that day. The Broncos, Green Bay Packers, Cincinnati Bengals and Oakland Raiders called him to express interest.
Denver made contact again with 15 picks remaining in the draft. The Broncos held the last pick and they told Sloter they would probably make him "Mr. Irrelevant," as that distinction has come to be known. About five minutes after that, Sloter's phone rang again. It was Denver, again.
"They said they wouldn't be (drafting me)," Sloter said. "But they were still really high on me."
The Broncos instead took Kelly, the former Ole Miss quarterback, with the last pick. Sloter and Kelly will eventually compete for a spot on Denver's roster, but for now, the Broncos' third quarterback job is Sloter's.
Sloter will be the only quarterback in the Broncos' rookie minicamp while Kelly recuperates from his injuries; Denver told Sloter it won't sign another undrafted quarterback.
He already has some familiarity with the Broncos' offensive staff. Denver quarterbacks coach Bill Musgrave is the former coach of D.J. Shockley, who was Sloter's quarterbacks coach in high school. Musgrave, like Sloter, is from Atlanta.
Sloter has completed the coursework for his finance degree, which he'll soon get in the mail, and took his last final Tuesday.
The Broncos signed him to a three-year preferred undrafted free agent contract that includes a signing bonus. That's an atypical contract, and it shows how highly Denver values him.
On Wednesday, Sloter will fly to Denver to put pen to paper and make the deal official. Then the real work begins.
"They told me they felt like they got the best undrafted quarterback in the country," Sloter said. "It just felt like a really good fit and a really good situation."
