Matt Nagy says he needs more time to evaluate whether Mitchell Trubisky has become a better quarterback over the offseason.

The Chicago Bears drafted Trubisky with the second overall pick in 2017.

"We don't have enough right now," Nagy said. "I wish I could tell you we had enough. But there's just not enough with where we're at. We need to see more. I can't give you a fair statement or opinion with that.

"I'm excited to see some more team periods. Maybe a little more red zone, some two-minute, four-minute, situational football to truly say that. I'd ask for a little bit more time on that with him. But again, the mental side of it, decision-making, where he's going -- so far, so good. But we want to now continue to just see that get better and better to where we have 100 percent accuracy with that -- with both quarterbacks. They're both competing the right way. But I would say, realistically, we just need a little bit more time to be able to compare it to the last two years."

The Bears signed Nick Foles to compete with Trubisky for the starting job in camp.
