"No sir, I don't believe those are true," Manziel said. "After last spring, Coach [Kevin] Sumlin kind of came to me and said, 'Hey, we have an in-house guy we want you to sit down and meet with.' I was more than happy and willing to learn whatever I could from him. I could sit down and have meetings with him, and those continued throughout the next couple years. Had a great relationship with him."
Manziel set a Southeastern Conference record as a freshman with 5,116 yards of total offense, the 10th-best season in NCAA history at the time. As a sophomore, he threw for 4,114 yards and 37 touchdowns to go with 759 yards and nine touchdowns rushing.
A man in demand these days, Manziel says he's turned to three-time Super Bowl winner Tom Brady for advice during the pre-draft process.
"For him to reach back out to me after I sent a text message to him was extremely cool," Manziel said of their communication. "[It was] kind of a really funny conversation at first, [then we] worked our way into a more serious conversation."
