There was a bit of a different mood Sunday when the San Francisco 49ers completed their first offensive drive of the day. Everything was clicking mighty well for C.J. Beathard who completed all his passes and Matt Breida tore things up with some vicious runs. But then the defense came on the field. And the Arizona Cardinals offense responded with this: A lot of questions after wereabout who to point the finger at for what is an unacceptable play. Well look no further than Adrian Colbert who bit on Cardinals wide receiver Larry Fitzgerald and opened things up for what happened. And Colbert was quick to own up to the mistake. In his post-interview Cheap Fred Warner Jersey , Colbert was quick to take the blame: After this play, the 49ers defense started to get together, but never quite found itself until after a second Cardinal touchdown put the 49ers into a hole they never quite managed to dig themselves out of. The rest of the day, the Cardinals benefited mightily from a dead 49ers offense that went kaplooey on more than one occasion while their own offense couldn’t muster much of anything beyond their first couple of drives.While it’s nice to see Colbert take responsibility for these things, one has to wonder if it falls more on him, the secondary Youth Brock Coyle Jersey , or someone who is calling the shots.49ers make 3 changes to unofficial depth chart, have one release to make The San Francisco 49ers PR department released their unofficial depth chart for Week 3 vs. the Kansas City Chiefs, and there are some changes of note. The key to this is the “un” in unofficial because this has little to no input from the coaching staff.This week’s depth chart includes George Kittle moved into the No. 1 tight end spot over Garrett Celek. This is not breaking news, but catching up with where things stand. Additionally, Matt Breida had previously been listed as the No. 1 running back, and Alfred Morris was listed as the No. 2 running back. It is now listed as Breida OR Morris. The 49ers are using a committee approach Youth Arik Armstead Jersey , so that make sense.This week’s most notable change is Reuben Foster added back in as the starting MIKE linebacker. Malcolm Smith is still listed as the WILL linebacker, but we don’t know if he will be healthy enough to play in Week 3, and even if he is, Fred Warner might supplant him on the depth chart.What is more important for the time being is who will be released to make room for Foster. While suspended, Foster did not count against the 53-man roster limit. The 49ers have to now figure out who to release in his place. The easiest choice would be linebacker Terence Garvin. The 49ers added him to the roster after Brock Coyle was placed on injured reserve, and he played 15 special teams snaps in Week 2. Even if Smith is not healthy enough to play Womens Jimmy Garoppolo Jersey , it makes sense to release Garvin. Foster would replace Elijah Lee in the starting lineup, and Lee would replace Garvin on special teams.49ers offensive depth chart, Week 3 vs. ChiefsPositionFirstSecondThirdPositionFirstSecondThird49ers defensive depth chart, Week 3 vs. ChiefsPositionFirstSecondThirdPositionFirstSecondThird49ers special teams depth chart, Week 3 vs. ChiefsPositionFirstSecondThirdPositionFirstSecondThird
