Jones spent the week impressing scouts until Saturday, when he was just 3 of 9 for 16 yards in the Senior Bowl game.
In an NFL Network interview Thursday, Jones said he called game officials a few weeks early to request a copy of the playbook.
Oklahoma's offense featured a high-tempo, no-huddle spread attack in 2012, leaving Jones with little huddle management opportunities, or chances to take snaps from under center, during his senior season.
“I wanted to show myself well here,” Jones said in the Thursday interview. “I wanted to be able to come back here and compete at the highest level.
“I didn't know what the playbook was gonna be like. ... I've played no huddle. I didn't want to be in the huddle, sputtering around and not know what I was doing. ... I felt like I did fine. There were only a couple instances where I had to ask for the play again.”
NFL Network analyst Mike Mayock asked Jones pointedly about his sometimes inconsistent play last season, specifically mentioning a fantastic showing in a late-season win at West Virginia, and poor play in the Sooners' Sept. 22 loss to Kansas State at home.
“Early in the season I was pressing quite a bit,” Jones responded. “Trying to make all the throws and play as perfect as I could instead of just cutting it loose and playing ball, going through my reads and not forcing balls down the field.
“I think that was the one thing that Kansas State taught me, that my career's really not in my hands. God has a team for me out there that's gonna pick me up.”
