Unofficial depth charts are exactly that. Unofficial.
There is usually very little truth that you can glean from an unofficial depth chart for the season, but the one the 49ers released Tuesday offers an updated glimpse of some of the key position's struggles throughout the competition.  Backup Quarterback
The new unofficial depth chart lists a & # 39; or & # 39; between CJ Beathard and Nick Mullens, which means it's a dead heat for the QB job, or at least that's what they would have you believe.
Beathard came to relief for Jimmy Garoppolo in San Francisco's 24-1
Still, while the Mullens came after Beathard, he did not waste his opportunity. The Mullens completed two of three passes on 27 yards and the 49ers' lone passing touchdown in the evening, a perfectly perfectly thrown bleach to Bourne in the back right corner of the end zone. It is also worth noting that the Mullens started San Francisco's first preseason game.
Expect Garoppolo to play the majority of the first half of the 49ers' third preseason game against the Chiefs on Saturday, if not all. Keep an eye on who's taking over for Jimmy G, as it can provide the best clue yet as to which direction Kyle Shanahan is leaning.
Marquise Goodwin and Dante Pettis are still listed as beginners. No surprise there. They, along with Trent Taylor and rookie Deebo Samuel and Jalen Hurd, are absolute locks to make the list. That leaves Bourne, Richie James Jr., Jordan Matthews and others fighting for what will be a maximum of two places, but more likely just one.
Based on the new unofficial depth chart, it seems that Bourne and James have the inner track to make the list, as they are listed behind the starters, respectively. Hurd is listed behind James Jr., while Matthews and Samuel are listed behind Bourne.
James seems too duplicitous of Taylor, but given that Taylor will miss the start of the season after breaking a leg in the foot, could open space for James, especially given his ability to return.
Bourne's promise was shown in his receiving touchdown against the Broncos. But as good as that catch was, his unfortunate drop of Beathard's deep ball was just as bad. San Francisco could use more size as a receiver position, as Bourne 6-foot-1 offers. But it's Matthew's 6-foot-3.
Matthews was targeted only once against the Broncos and had zero receptions, but he played 14 snaps on special teams, including one where he took down the score for a two-yard loss. Anyone who makes the team as the final receiver must play special teams. Matthews definitely did not hurt his case in that area, and the veteran stability he offers will surely be contrasted with Bourne's inconsistency.

The updated unofficial depth chart lists Adrian Colbert as the starter , though with the injured Jimmie Ward understood to be the starter on his return. Behind Colbert, in order, are Tarvarius Moore and Antone Exum Jr..
In two pro seasons, Colbert has missed a total of 11 games due to injury. He suffered a hamstring injury against the Broncos and has generally underplayed throughout the training camp.
With Ward on the side and Colbert not claiming the job in his absence, it opened the door for Moore, as the 49ers – in desperation – were forced to switch to safety after being a cornerback his rookie season. Moore played security at the college and has shown some promises there recently, but that's not a good sign when it's possible that your best free safety alternative spent the entire previous year learning a different position. Given Ward's long injury history and how the depth chart currently looks, one continues to wonder if San Francisco will regret not having received a single security in what was charged freely by agents and draft classes at that position.
