49ers offensive line roster bubble

Lock: Aaron Banks, Jake Brendel, Spencer Burford, Jon Feliciano, Colton McKivitz, Trent Williams
Strong bubble: Jason Poe, Matt Pryor, Nick Zakelj
Weak bubble: Keith Ismael, Corey Luciano*, Ilm Manning*, Jaylon Moore, Leroy Watson
Long shot: Joey Fisher*, Alfredo Gutierrez,

Interestingly enough, San Francisco's starting offensive line is set from left to right with Trent Williams, Aaron Banks, Jake Brendel, Spencer Burford and Colton McKivitz holding down those respective roles.

Burford and McKivitz will be enjoying the reputation of full-time starters for the first time, so that'll be fun to watch.

But the real position battles here are for depth.

Swing tackle is a question mark, and it could go to one of the uber-linemen the 49ers grabbed during the offseason, Jon Feliciano, who helps make up for the free-agent loss of another versatile commodity, Daniel Brunskill, whom the Niners used to employ prior to this offseason.

Brendel also needs a backup center, too, which means Corey Luciano might actually turn some heads if the snapping experiment with Nick Zalelj doesn't pan out (it hasn't so far).
