"I'm where I need to be (physically) right now," the free-agent wide receiver told Mike Fisher of CowboysSI.com. "I'm more serious than ever."
Bryant sat out the 2019 campaign while rehabbing from a torn Achilles, which he sustained at his first practice with the New Orleans Saints last season. The 31-year-old spent the first eight years of his career with the Cowboys and holds the franchise record for career touchdown receptions with 73.
Bryant endured a somewhat messy divorce with the Cowboys because of his disdain for head coach Jason Garrett. He said he wouldn't be limited to running short routes like a tight end for Dallas in 2020 "because Garrett is gone."
"I know I would respect my role - and make a huge impact," he added.
Bryant had 69 receptions for 838 yards and six touchdowns over 16 games for the Cowboys in 2017.
