"I have the same impression when he came out of [Texas] A&M of what his potential is as a football player," Jones told King. "But you can be the smartest mathematician, you can be the greatest politician, but if you can't get it straight with your life, you don't get those chances. And so I'm more concerned with that, and with that in mind, not thinking about where [he] is to football and the Cowboys."
Jones responded to King when he asked if the team would be interested in Manziel if he got "his life in order."
"Well, I haven't changed my opinion of how exciting a player that he is, how unique a player that he is," Jones said. "And he plays a unique position."
Manziel was released by the Cleveland Browns last week.
"We have an old adage in talent evaluation: If you see them do it a couple times, they can do it," Jones told King. "Now, will they have the discipline and the will to get out there and do it day in and day out, do like a Peyton Manning and make a career out of doing it every day. That hasn't been shown." The Cowboys passed up Manziel to select Notre Dame guard Zack Martin, with the No. 16 pick in the 2014 NFL Draft. Manziel was picked at No. 22 by the Browns.
"As it would turn out, he's had a disappointing life experience, as it would pertain to his time in the NFL," Jones said on DallasCowboys.com. "I do respect him as a player and a talent. I want to talk about any way he could help that."
Manziel, 23, has had a disappointing encore to his 2013 Heisman Trophy winning season. He completed 18-of-35 passes for 175 yards and two interceptions, leading to a 0-2 record in his rookie campaign. Manziel followed up last season by completing 129-of-223 passes for 1,500 yards, seven touchdowns and five interceptions, leading to a 2-4 record.
