Although quarterback Collin Klein impressed coach Gary Kubiak at the Houston Texans' rookie minicamp last weekend, the Heisman Trophy finalist wasn't offered a contract by the team.
Klein, who finished third in last year's Heisman Trophy voting, insisted on working out only at quarterback in advance of the NFL draft despite his unorthodox throwing motion, passing up opportunities to let scouts look at him at tight end or receiver.
The former Kansas State quarterback ended up going undrafted and accepted the tryout invitation from the Texans.
"I don't want to get too far ahead of myself, but to watch how far the guy came in two and a half days ... probably had his best day out there today," Kubiak told reporters Sunday. "He's found a way his whole career, and he's probably gonna find a way this time, too. He's done a good job."
The Texans have four quarterbacks on their depth chart, led by starter Matt Schaub. The other signal-callers are T.J. Yates, Stephen McGee and Case Keenum, who went undrafted in 2012 and spent the season on Houston's practice squad.
"For what he did in college and what Jake has been doing with him, he's come a long way as far as working under center and stuff," Kubiak told reporters, according to the Texans' website. "The arm strength is there. The delivery's a little different, but you work with that. His instincts as a football player, you can't coach, the way he just takes off and stuff like that."
Klein told KRIV-TV in Houston that he was grateful to get the chance to try out.
"I feel very good that I put my best foot forward and just so grateful they gave me the opportunity," he said.
