There are a robust number of story lines heading into Vikings training camp. Most of them revolve around Percy Harvin, Adrian Peterson, Christian Ponder, the secondary and rookie left tackle Matt Kalil. One thing is for sure, Ponder has matured as a leader, according to GM Rick Spielman.

Vikings' wide receiver Jerome Simpson says fans can expect 100 percent effort from him all the time. Quarterback Christian Ponder says Simpson's athleticism will bring a lot to the team.

Vikings quarterback Christian Ponder appears to have the inside track on what's going on with his disgruntled teammate, Percy Harvin. Ponder told the Pioneer Press Saturday that he's been in touch with Harvin through texts. Ponder said while he's never brought up Harvin's problems with the organization, he knows the wide receiver is preparing for this week's training camp and is "ready to go."

The Vikings wrapped up their first full practice on Friday in Mankato. Christian Ponder was sharp throwing the football, Kyle Rudolph was catching everything and rookie cornerback Josh Robinson left with an apparent hamstring injury.

Christian Ponder's offseason is completely different from last year. Without a lockout, he's entering his second year with a full offseason, and he's taking advantage of it by working hard in the weight room.

Christian Ponder wasn't surprised when he was taken out of last Sunday's game in Detroit. The rookie quarterback admits he needs to "show improvement" and "do a better job of holding onto the ball." Ponder's counterpart this week, Drew Brees, says young players "got to face adversity."

Christian Ponder set Viking rookie passing records for yardage, attempts and completions Sunday. But two costly interceptions led to 10 points for the victorious Broncos, ruining Ponder's day.
