The San Francisco 49ers released their first unofficial depth chart of the preseason and, unlike last year, there aren't any shockers when it comes to the listed starters. The team is entering season two of a rebuild and is a year removed from a roster that had battles at several positions. While preseason depth charts don't mean a whole lot to begin with, it was interesting to see how the team was listing players at each position last year.

This year, fans pretty much know who will start at every position except right guard. In case you were wondering, Joshua Garnett is listed as the starter at that position with Jonathan Cooper as his backup. Of course, a knee injury has prevented Garnett from practicing since July 28. Cooper is working his way back from MCL surgery in January.

"That's the one (position where) we've got the most competition at, that's for sure," head coach Kyle Shanahan said on Sunday, "and two of the guys who should be right in that competition aren't practicing fully yet. Obviously, they haven't been in it, but it's given other opportunities to guys like (Erik) Magnuson, guys like (Mike) Person."

Another interesting note is that both Raheem Mostert and Joe Williams are listed together as the No. 3 running back. The two are battling for that third running back spot.
