Leslie Frazier has said that Christian Ponder is "more confident" as he prepares for his third season in the NFL.
The quarterback helped the Minnesota Vikings reach the playoffs for the first time in three years last season.
Speaking at a press conference, the team's head coach said: "I think what I've seen is better command, a guy who's more confident in what he's doing. You'd expect that with it being his third year in the system, but it's great to see. I can see him taking more control in the huddle, interacting more with teammates other than just that small group of guys he's comfortable with.
"His knowledge of our offense, and the command that he's displayed, and these last few practices have been some of his best practices from a decision making standpoint, as well as how he's handled himself around the huddle.
"Seeing some growth and I'm looking forward to seeing how he plays on Friday night, and continue to grow. The growth and leadership is what's been impressive."
The Vikings face the Buffalo Bills tomorrow evening.
