The Minnesota Vikings can’t seem to make up their minds about Tommy Armstrong.

At first, the former Nebraska quarterback joined the Vikings’ rookie minicamp as a running back. By the time the weekend finished, he was moved to safety. Armstrong tweeted that he was told the team wanted him to come back and play safety.

On May 11, Armstrong was told they didn’t have a spot for him. Less than three weeks after that, the Vikings brought him back and signed him as a safety.

But wait, there’s more.

On Friday, the Vikings announced that they waived Armstrong. That was after the team conducted its three days of mandatory minicamp.

In the last five weeks, that’s the fourth time the Vikings made a roster move involving Armstrong.

What does that mean for the former Nebraska signal-caller? Perhaps he’ll get picked up off waivers and make a different 53-man roster. What remains to be seen is whether or not he’ll continue to try out at safety.

There’s still a learning curve for Armstrong, who is trying to play the position for the first time since high school.

“You can see some of the traits we look for in defensive players,” Vikings Mike Zimmer said of Armstrong earlier this month via the Star Tribune. “Obviously he is still trying to learn some of the basic techniques of things and that will take a while, but he is a good, quality kid to work with.”

Maybe those qualities will earn Armstrong an opportunity to stick somewhere else.
