Most significant move. The San Francisco 49ers' decision to keep running back Anthony Dixon played into a broader special-teams theme. Veteran fullback Rock Cartwright, once seen as a key special-teams addition following Blake Costanzo's departure in free agency, received his release. The 49ers traded another core special-teams player, safety Colin Jones, to Carolina for what was thought to be a 2014 seventh-round choice.
The 49ers' decision at quarterback was also among those I found most significant. The team kept Scott Tolzien over Josh Johnson in the No. 3 role even though Johnson played for 49ers coach Jim Harbaugh at the University of San Diego. Johnson also outplayed Tolzien in the final exhibition game. Keeping Tolzien appealed, however, because his ceiling appears less defined. Johnson has played in the NFL without setting a sharply upward career trajectory. Colin Kaepernick's emergence as a stronger No. 2 quarterback bought some insurance for carrying a less-experienced third-stringer, perhaps.
Onward and upward: Linebacker Michael Wilhoite, offensive lineman Mike Person and safety Michael Thomas appear to be young players with futures in the NFL. Defensive lineman Matthew Masifilo impressed in the final exhibition game. The 49ers' practice squad will be an option for some of the players let go, but I won't be surprised if waiver claims from other teams get in the way. The 49ers have done a good job building talented depth throughout their roster.
The team also released Eric Bakhtiari, Ikaika Alama-Francis, Derek Hall, Joe Holland, Tony Jerod-Eddie, Cam Johnson, Anthony Mosley, Kyle Nelson, Al Netter, Chris Owusu, Nathan Palmer, Konrad Reuland, Kenny Rowe, Brett Swain and Kenny Wiggins.
Reuland could get another chance. It was a mild surprise, perhaps, to see Garrett Celek stick ahead of Reuland as the third tight end.
What's next: The 49ers will watch closely to see which players clear waivers. Wilhoite is one they would like to re-sign, according to his agent, but teams looking for young depth at linebacker could submit claims. The team could use another outside linebacker, at least on paper, but the 49ers got through last season with only three of them.
The 49ers are carrying only eight offensive linemen. Their swing tackle, Alex Boone, is starting at right guard. If there's an offensive tackle out there worth claiming, the 49ers could consider adding one. But two of their division rivals, Arizona and St. Louis, have greater needs and higher waiver priorities.
