Justin Smith Retirement Latest Blow in 49ers' Nightmare Offseason

The San Francisco 49ers are the NFL's version of the Tin Man. The organization is now a shell of itself, and it lacks heart. 

Earlier in the offseason, the franchise lost its soul when linebacker Patrick Willis retired. The heart of the team was ripped out Monday once defensive end Justin Smith decided to retire after 14 stellar seasons, the Niners announced via Twitter.  

Even after four straight years of diminished snap counts, Smith's toughness and tenacity were still legendary in NFL circles. As ESPN.com's Chris Sprow noted, Smith was a constant along the defensive line throughout his career: 

It wasn't simply dominant play, even though there was plenty of that. After all, Smith was a five-time Pro Bowl selection and three-time All-Pro defender. There was arguably no better defender in the NFL for a span of four seasons between 2008 and 2011. 

How many defenders in the NFL's history could walk a left tackle all the way back to quarterback then complete the sack by using only one hand? Very few. Smith was one of them, as SanFrancisco49ers.com's Taylor Price reminded everyone: 

But Smith's impact extended beyond his on-the-field prowess. He set the tone for the team with his attitude and work ethic. 

Vic Fangio served as Smith's defensive coordinator for the past four seasons. The current Chicago Bears assistant coach described the defensive lineman's approach to his craft in a December interview with the Sacramento Bee's Matt Barrows:

"

I think the one thing that defines him is that he’s just a true warrior in the truest football sense of the word. He played a whole season last year with half an arm. There are a lot of guys that wouldn’t have even gone out there. But the guy loves football, loves playing, loves competing. He’s definitely in my personal top three or five hall-of-fame (players) that I’ve been around.

"

Of course, the 49ers downplayed the significance of the loss because, frankly, they have to at this juncture. Head coach Jim Tomsula provided a lackluster plan to replace a team leader and all-time great 3-4 defensive end, courtesy of Barrows: 

"

For four years—you see the D-linemen we’ve brought in—we’ve been making preparations. This isn’t a this year thing for us. We’ve been making preparations. A guy (Smith) gets to 12 years in the National Football League and he’s about a 92-percent rep count playing defensive line, you better start making preparations. That started a while ago.

"

There are some players who simply can't be replaced. Smith is one of them. Tomsula acknowledged as much, per the San Jose Mercury News' Cam Inman.

But the 49ers will try with this year's first-round pick, Arik Armstead, as well as Tony Jerod-Eddie, Tank Carradine and an almost 34-year-old Darnell Dockett, who signed with the team this offseason after suffering a torn ACL in 2014. 

It's not exactly an inspiring group after Smith dominated for years with the likes of Willis, NaVorro Bowman, Aldon Smith, Ahmad Brooks and Ray McDonald surrounding him. Three of those six players are either retired or will be playing for other teams in 2015. Only three defensive starters from Super Bowl XLVII remain on the roster. 

Smith's retirement is merely the crescendo to a franchise-redefining offseason. 

In a span of four months, this organization pales in comparison to the one that made the NFC Championship Game in three straight years from 2011 to 2013. 

The bad blood between former head coach Jim Harbaugh and general manager Trent Baalke festered and eventually poisoned the Bay Area waters. An 8-8 campaign last year proved to be enough of an excuse for the team to mutually part ways with Harbaugh. 

For most teams, the loss of a highly successful head coach—who was 44-19-1 during his four seasons in San Francisco—to office politics and hurt feelings would be the depths of its offseason woes. 

But not the 49ers. It was merely the beginning. 

First, the organization hired Tomsula to be its next head coach. The team's brass seemed enamored with the former defensive line coach, and his hire almost appeared to be a power play after working with Harbaugh the previous four seasons. Now the franchise will rely on a former assistant who never served as a full-time head coach at any point during his 26-year coaching career. 

Just as 49ers fans started to get comfortable with the idea of Harbaugh no longer being the head coach, the team's net losses during free agency when compared to its gains were troubling. McDonald, running back Frank Gore, guard Mike Iupati, cornerbacks Chris Culliver, Perrish Cox, linebacker Dan Skuta and wide receivers Michael Crabtree and Stevie Johnson all signed with other franchises. 

In return, the team signed wide receiver Torrey Smith, cornerback Shareece Wright, running back Reggie Bush and the aforementioned Dockett to offset some of its losses. 

Bigger blows to the roster were also on the horizon. 

With free agency set to begin, Willis, a seven-time Pro Bowl selection, made the same decision as Smith. After eight years in the league, injuries caught up with the transcendent talent and forced him to shut it down.

Yet the organization could overcome the adversity once Bowman was healthy and with promising rookie linebacker Chris Borland ready to take over at inside linebacker.

Borland decided to retire, though, five days after Willis due to growing concerns over his health. Borland was one of the NFL's finest rookies in 2014, and his level of play helped the team cope with the absence of Bowman, who missed the entire season with ACL and MCL injuries.

Borland's decision caught Baalke and the organization off guard. 

Despite these losses, Pro Bowl safety Antoine Bethea believes the 49ers can continue their winning ways, per ProFootballTalk.com's Josh Alper:

"

It’s going to be fine. I have no worries about that. I think last year, I think there was a lot of talk about our secondary, but I think our secondary did pretty good last year. We’ve got a lot of young guys. [Cornerback Tramaine] Brock is healthy and once we come together, get this camaraderie together out here working, pushing each other, get these OTAs, minicamps and all that, I think we’ll be fine. …

I’m pretty sure we’re going to have guys that are going to step in and play some great football for us, getting NaVorro [Bowman] back this year. We’re going to get some guys to come in and step in and make some plays. We’re going to be a family out there and we’re going to do what we need to do.

"

No, it's not going to be fine, Mr. Bethea.

While a team should always aspire to achieve greatness, the type of losses the 49ers suffered this offseason will likely prove to be insurmountable, especially in the highly competitive NFC West. 

A franchise—no matter how talented it is overall—cannot truly overcome the departures of two All-Pro defenders, the franchise's all-time leading rusher, a Pro Bowl guard and a top-flight head coach, particularly when all of that occurs in the same offseason. It's simply too much. 

The 49ers organization is trending in the wrong direction, and it likely made Smith's decision to retire a little easier.
