MIAon offense San Francisco 49ers Hoodie , the Miami Dolphins even decided to switch snappers.Three-time Pro Bowl center Mike Pouncey was released Thursday as part of an offensive line makeover. Miami also acquired center Daniel Kilgore in a trade with San Francisco, and four-time Pro Bowl guard Josh Sitton agreed to terms on a two-year deal that could be worth nearly $18 million including incentives, said his agent, Jack Reale.Pouncey, 28, has been plagued by serious problems with both hips, and at one time said he feared the issue might be career-ending. But last season he played in all 16 games for the first time since 2012.The Dolphins also sealed their deals with former New England Patriots receiver Danny Amendola and former Kansas City Chiefs wideout Albert Wilson. They re-signed defensive back Walt Aikens, a standout on special teams, and re-signed long snapper John Denney, who has been with Miami since 2005 and turns 40 in December.Quarterback David Fales agreed to terms on a one-year deal and could win the backup job behind Ryan Tannehill. Fales threw for 265 yards in last season’s finale against Buffalo and won praise from coach Adam Gase.Pouncey became the fifth starter jettisoned by Gase after a 6-10 season. Five-time Pro Bowl defensive tackle Ndamukong Suh was released, as were linebacker Lawrence Timmons and tight end Julius Thomas, and three-time Pro Bowl receiver Jarvis Landry was traded.Changes on offense were expected after Miami ranked 28th in points last season.Pouncey, a first-round draft pick by the Dolphins in 2011, made the Pro Bowl in 2013-15. But he never played in a playoff game and was at the center of team’s bullying scandal in 2013.Kilgore is a seven-year veteran who started all 16 games for the 49ers in 2017. Last month they signed him to an $11.78 million, three-year contract extension, but he became expendable when San Francisco signed free agent center Weston Richburg to a $47.5 million, five-year deal this week.As part of Miami’s trade with the 49ers, the teams swapped seventh-round draft picks.Sitton, 31, spent the past two seasons with the Chicago Bears and made the Pro Bowl most recently in 2016. He played for the Green Bay Packers from 2008 to 2015 and has 137 career starts.Amendola signed a $12 million https://www.49ersfanshop.com/Deion-Sanders-Jersey , two-year contract, and Wilson received a $24 million, three-year deal. They’ll combine to replace Landry, who has a $16 million franchise tag for this year.Amendola, 32, is a nine-year veteran with 426 receptions, including 61 last season. Since 2013, he has played in 13 postseason games with Tom Brady. Wilson is a four-year veteran with 124 career catches – a dozen more than NFL leader Landry made last season.— This has been a rough year for the Faithful, between injuries, close losses and the underwhelming development of several highly-touted young players on the San Francisco 49ers roster.Most see these problems as temporary, with the combination of Kyle Shanahan’s offensive schemes, Jimmy Garoppolo’s arm, and a high draft slot for GM John Lynch combining to paint a bright future.Is it time to question that future, though? The 49ers have struggled offensively this year, scoring under 20 points in four of the last six games. Could it be that Kyle Shanahan’s offense is not as great as everyone hoped it would be? Offensive wizards can get figured out in this league (just ask Chip Kelly).Let’s start by acknowledging what we don’t know — the exact plays, reads and defensive coverages on each play. Deception is a big part of the battle between offensive and defensive coordinators, and unless you wiretapped the helmet mics during the game, none of us really know what the calls were.That said, Shanahan’s offense is pretty simple in some ways — a lot of outside zone runs mixed with play action. While he’s innovative in moving skill players around his formations and good at getting production from all of them — including his fullback — Shanny’s scheme is more multiple than tricky.This should keep him relatively immune from being “figured out” in general terms, but it moves the battle against defensive coordinators into individual game plans and player matchups. The commonly used metaphor of football as a chess game doesn’t really work Joe Montana Color Rush Jersey , because talent changes everything. In football, one “knight” might be able to move three squares down and three over; another could go four down but can’t cut to the right.The problem is that injuries and a general shortage of talent have left Shanahan with little to work with. We can’t really tell if a play is creating lots of possibilities, when the surviving players aren’t capable of executing it. The loss of Marquise Goodwin in particular has been a huge issue, allowing defenses to collapse and removing Shanahan’s deep shots from his arsenal. Pierre Gar莽on’s injuries have compounded the problem.Matt Breida, Nick Mullens, and Jeff Wilson, Jr. have overachieved beyond anyone’s wildest dreams, which is a great sign of the power of Shanahan’s scheme (and Bobby Turner’s coaching of the running backs). But there are reasons why each was a UDFA, and in general any DC would rather game plan against them than Garoppolo, Goodwin, and Jerick McKinnon.If you look at production during games, there are encouraging signs. Even with all of their problems, the 49ers are 15th in the league in offensive yards per game (363.3), and 7th in running yards (129.2). However, they are 21st in point per game (21.3), which points both to turnover problems and red zone weakness. The very young skill players, with less experience against top-level competition, are vulnerable on both scores.What we are not seeing is some kind of schematic adjustment that undermines the advantage of Shanahan’s scheme, the way that, say Y.A. Tittle Jersey , scrape exchanges countered read-option run plays. When the offense stalls, it’s the result of errant passes, illegal motion and holding penalties, or sacks.Tampa Bay threw a lot of pressure at Mullens, and his greenness showed. He felt the pressure and couldn’t get the ball to open receivers in many cases. It’s worth noting that Tampa Bay’s offensive coordinator, Todd Monken, was Mullens’ coach at Southern Mississippi. So they had extra insight in the rookie QB’s vulnerabilities.Against Seattle, Shanahan dialed up a lot of screen passes, which were effective in helping Mullens handle the predictable pressure. This hasn’t been a big part of Shanny’s scheme, even though opposing coaches such as Andy Reid have been torturing this team with screens all year. Shanahan, in my opinion, prefers taking shots downfield or between the numbers in these situations, to move the ball downfield more aggressively, but he’s limited by wide receiver injuries, and doesn’t have a quarterback capable of finding the receivers he has. This was a necessary adjustment, but I don’t think we’d see that with healthy starters.We won’t know for sure if Shanahan is less than his reputation would suggest until next year, with a talent infusion and healthier players. It’s the job of coaches to make the most of what they have, but Shanahan is facing extreme limits. It’s possible he’s a guy who needs top level talent (say, Matty Ice and Julio Jones) to really do well. But I think 49ers fans would prefer that to a coach who specializes in getting more than you’d expect out of a bunch of bad players. Jed York and the 49ers front office show every sign of wanting to get back to the Super Bowl and having a pretty good plan for getting there. It just might take a bit longer than we hoped.
