"Yeah, I think it's close," Witten told the Fort Worth Star-Telegram's Clarence E. Hill Jr. "(They have) the most talent I've seen."
The 36-year-old tight end retired abruptly last April to take a broadcasting job on Monday Night Football. He came out of retirement equally suddenly, as the Cowboys announced Feb. 28 that he would rejoin the team.
"It was a long nine months away, and I think we all know how we go into making those decisions like that," Witten said. "It's great to get back in there. And having those captains' workouts really allowed me to fit in. Within the first five minutes, it's like 'OK, this is new for a second.' But getting acclimated with those guys, (getting) back to work, (putting) your head down. That's how I tried to approach it. So it's been a good start. I know I have a lot of work still to do."
Witten caught 63 passes for 560 yards and five touchdowns in 2017. Dallas is coming off a year in which it captured the NFC East title and won its first playoff game since 2014.
