Sam Bradford shared a practice field with Carson Wentz for the first time on Tuesday.
Bradford also talked about the approach he took in requesting a trade.
"When I first found out about the trade," Bradford said, "I was frustrated. I needed some time. I could have stayed here, but I'm not sure my head would have been here."
Bradford sign a two-year contract with the Eagles in March believing he would have the chance to establish himself as the long-term quarterback.
"Obviously, there are no promises in this business," Bradford said. "It wasn't a long-term deal, it was a two-year deal. I was well aware of that. We talked about that.
"My thought was to play well over that two years and to create that stability that I've talked about pretty much my whole career. Philadelphia was the place that I wanted to be. I wanted to play well for the next two years, create that stability and then sign a longer-term deal and stay here, for the rest of my career."
Once the Eagles traded for Wentz, that became a near impossibility.
"My agent felt a trade was the way to get somewhere to create that stability, at a place where I could be entrenched long term," Bradford said. "He felt that was the best option."
