"I think he's going to end up going to the Green Bay Packers," Witten told ESPN's Adam Schefter, via the Fort Worth Star-Telegram. "I think that's a great spot for him. Aaron Rodgers, he throws that back-shoulder throw so well, and Dez (can have) great chemistry with a good quarterback that can put the ball wherever he wants."
Witten added that new arrival Jimmy Graham and Bryant could be a boon for Rodgers and the Packers.
"I still think Dez can still high-point the football as good as any other wide receiver in the National Football League," Witten said. "You partner him up with Jimmy Graham and Aaron Rodgers, and I think that offense can put up a lot of points. ... I think it's a win-win for the Packers."
Green Bay also utilizes wide receivers Davante Adams and Randall Cobb in the passing game.
Bryant, however, recently dismissed the notion of going to the Packers -- citing "too much history."
The three-time Pro Bowl selection is referring to his apparent catch during the fourth quarter of the 2014 playoffs that was ruled an incomplete pass after he failed to maintain possession of the ball while going to the ground. The Cowboys went on to lose that game in Green Bay, and the "catch" rule was changed by the NFL this offseason.
Bryant reportedly hasn't drawn much interest since he was released by the Cowboys on April 13 after eight seasons with the team. The 29-year-old reportedly turned down a multiyear offer from the Baltimore Ravens prior to the 2018 NFL Draft in a bid to find the right fit on a one-year deal that could help secure a bigger contract the following year.
Witten added another potential landing spot for Bryant: the New Orleans Saints.
"I tell you another team he could go to is Drew Brees and the Saints," he said. "That's a vertical passing attack, they need somebody who can stretch the field and that X-factor is Dez Bryant."
Dallas added wideouts Allen Hurns, Deonte Thompson and Tavon Austin in the offseason and selected Michael Gallup in the third round of the draft. The group joins Terrance Williams and Cole Beasley on the Cowboys' roster.
Bryant had a team-leading 69 receptions for 838 yards and six touchdowns with Dallas in 2017. He has gone a career-worst 23 regular-season games without a 100-yard performance.
Since signing a five-year, $70 million contract in 2015, Bryant has failed to record a 1,000-yard season or reel in more than eight touchdown receptions in a season.
Bryant was a touchdown machine in the first half of his career with the Cowboys, hauling in 41 scoring passes in a three-season span, capped by a career-high 16 in 2014. He was named a First-Team All-Pro selection that year.
During that spectacular run from 2012-14, Bryant also averaged 91 receptions and put up at least 1,233 receiving yards in each of those seasons.
