Bowles was asked at a press conference whether he thinks Darnold is a franchise quarterback after Monday night's 48-17 beatdown of the Detroit Lions.
"We won one game, I can tell you after about 100 more of them whether we have one or not, right now it's a little early," Bowles said, according to the team transcript.
The 2018 third overall pick threw for 198 yards and two touchdowns in his regular-season debut while completing over 76 percent of pass attempts. He quickly recovered from an interception that was returned for a touchdown on the first meaningful pass of his NFL career.
Bowles said mistakes like that will help Darnold learn and grow.
"Obviously, (we're) starting him, he can play the position. He's got to go through some things like he will every week, every week will be different for him just like everybody else on the team that's young. You grow with the position, he's not green he's very sharp, he handles himself very well and I trust him to make adjustments as he goes."
Darnold will take the field for his second start in the Jets' home opener on Sunday against the Miami Dolphins.
