ASU alum Tyrell Johnson to compete for Vikings starting safety job

MANKATO, MN ( - A lot of people are disappointed in how Tyrell Johnson's once-promising NFL career has unfolded to this point. Add him to the list.

"Things didn't go as planned for me last year, or, really, anytime since I've been here," Johnson said Sunday at the start of training camp. "But the way I look at it is I've got a tremendous opportunity."

Among this year's position battles is free safety, where veteran Madieu Williams was released in a salary cap move. Johnson, Jamarca Sanford and rookie Mistral Raymond will compete for the job, coach Leslie Frazier said Sunday.

"It's an open door right now, which is good for our ... team," Frazier said. "It's healthy competition, and we're going to try to identify the best two guys."

While Sanford and Raymond were late-round draft picks, Johnson was a second-round pick out of Arkansas State in 2008. The Vikings thought enough of him to trade a fourth-round pick to move up for him.
