Massaquoi, who was claimed off waivers from the Falcons earlier this year, is recovering from shoulder surgery. He had a bone spur removed from the area, but the procedure was categorized as a minor cleanup.
Massaquoi recorded 22 tackles in 15 games with Atlanta last season.
"He did a lot of the things that we thought he would do very well,” coach Ken Whisenhunt said during an interview Tuesday with 104.5 The Zone, per ESPN.com. “There were some points where he struggles terminology-wise just because of the volume of it. He threw the ball well, he moved in the pocket very well, he took snaps with no problems.
“There were a lot of things that he did really well and there were a lot of things that a lot of young players struggle with in a first minicamp. So overall I would say we’re very excited about what he did.”
While Whisenhunt liked a lot of what he saw from Mariota, he was most impressed with how he did with his outside throws.
“I think getting a chance to see him throw some of the combinations in the pocket, making some of those throws, I thought was better,” Whisenhunt said. “Especially some of the outside throws on the corners, the comebacks, the stops, those things outside.
“He did a nice job with his footwork and how he drives the ball out there. I was impressed with that. You watch them in their workouts but you don’t really get a sense of it for sure until you see them doing it in your system. So that was pretty impressive."
"I'm working at it," he said, per ESPN. "I feel comfortable at everything right now. I thought in practice it went well. It's just getting repetition at it. ...The biggest difference for me right now is when you're under center, you're really close to the front and it take a little more to see maybe the backend in terms of the secondary. Other than that, your drops are still the same, the play-action stuff is still pretty much the same. It's playing football."
Mettenberger has declared that he will "fight to the death" for the job he earned last season. He knows that second overall pick Marcus Mariota stands in his way and that some believe the latter is all-but-set to start. But he also feels that as long as he doesn't believe it, he has a chance.
"I don't know what the mindset is, but at the end of the day I can just control what I do and I'm extremely confident in myself, almost to a fault," Mettenberger told ESPN. "People who know me know I'm not going down without a fight to the death."
Among those who believe it are teammate and tackle Taylor Lewan, who expressed his view to ESPN that Mettenberger will put up a good battle for the job.
