No. 8: Linebacker Ray-Ray Armstrong

A year ago at this time, linebacker Ray-Ray Armstrong was on his way to securing a starting spot in the 49ers’ then-3-4 defensive alignment. Armstrong’s solid play helped earn him a two-year extension through 2018.

But a pectoral injury in Week 2 negated the rest of his 2016 campaign, and the Niners have all but overhauled this unit.

In addition to a healthy NaVorro Bowman, the 49ers brought in free-agent linebacker Malcolm Smith and rookie Reuben Foster to reinforce this dilapidated unit.

Such moves could push Armstrong out of the equation this season.

What works in Armstrong’s favor, though, is his better-than-average coverage abilities. Perhaps San Francisco sees some value here and elects to keep him for both this and a possible role on special teams.

Still, Armstrong will have a long way to go to ensure a roster spot.
