After a lengthy stretch of contemplation about retirement or playing a 14th season, Alex Mack looks to have decided on the former. The decorated center is set to retire, Michael Silver of Bally Sports reports (on Twitter).
This will cap Mack’s 49ers tenure at one year and give the team another interior offensive lineman to replace. Mack started all 20 49ers games last season, rejoining Kyle Shanahan after the two previously linked up in Atlanta and Cleveland. Mack finishes his career as a seven-time Pro Bowler.
The 49ers have had extensive time to prepare for this outcome and gained around $4MM in cap room by reducing Mack’s contract and moving $500K up to a June 2022 payment. Mack, 36, signed a three-year deal worth $14.85MM in 2021. That telling transaction will allow the 49ers more flexibility to potentially sign a Mack replacement, though Jimmy Garoppolo‘s $26.9MM cap hold has clogged San Francisco’s payroll for a while. It does not look like that figure will come off the team’s books in the near future, and the team entered Thursday ranking 31st in cap space. Mack’s adjustment still stands to help.
The Browns drafted Mack in the 2009 first round, and he delivered three Pro Bowl seasons in six Cleveland years. The Cal alum enjoyed an interesting offseason in 2014, when the Browns transition-tagged him and Jaguars submitted an offer sheet. The Browns matched the five-year, $42MM offer, but that deal gave Mack the right to opt out after two seasons. He did, doing so in 2016 en route to rejoining Shanahan — his Browns OC in 2014 — with the Falcons. The Falcons gave Mack a five-year, $45MM deal, giving Matt Ryan a quality center ahead of a key season.
Atlanta’s Shanahan-conducted 2016 offense scored 540 points, which still ranks eighth in NFL history. Mack earned the second of his three second-team All-Pro nods, helping Ryan claim MVP honors. This season ended infamously in Super Bowl LI, but Mack made the Pro Bowl in his first three…
