The quarterback, who was named the AFC offense player of the week, completed 199 passing yards and three touchdown passes during the team's 30-28 win over the Atlanta Falcons earlier this week, leaving them just one win behind AFC East leaders the New England Patriots.
The rookie told reporters: "You know, I think we've always carried a swagger. I think we believe in ourselves. It trickles down from our head coach. He's a type of guy who's very confident and he's confident in his troops, so we've always had that.
"Right now we're just focused, we're extremely focused, and you can tell it by the vibe of the guys around here. Everyone's focused in on what they want to do and what we need to do as an offense and as a team. And we're steadily getting better.
"As an offense we still have things to improve on. We still have some things that we need to get better at and we need to go out there and showcase on the field. We're just steadily trying to improve."
