It makes all kinds of sense to think the San Francisco 49ers would have red-hot interest in Tampa Bay Buccaneers star defensive tackle Vita Vea after he requested a trade after failing to come to a contractual agreement with the Bucs.
Despite a notably successful offseason already, including landing one of Vea's former teammates in Tampa, wide receiver Mike Evans, the Niners are still widely viewed as the "third fiddle" within the NFC West, trailing both the star-studded Los Angeles Rams and Super Bowl-champion Seattle Seahawks.
In particular, L.A.'s blockbuster trade for the reigning Defensive Player of the Year, Myles Garrett, only fuels the division's arms race and puts pressure on San Francisco to respond.
Hence why Vea makes sense. He's a space-eating run stopper with enough pass-rushing prowess to make life hell for opposing blockers. Paired with another 49ers offseason pickup, Osa Odighizuwa, the defensive front could soon rival that of Los Angeles.
But, a trade would come at an exceptional cost. Potentially a Christian McCaffrey-sized cost.
Assuming the Niners have enough draft capital to make a trade with the Buccaneers (they do), the next question would be meeting Vea's contractual demands. That's not a problem in 2026, as San Francisco currently leads the NFL with over $71 million in cap space, per Over the Cap.
However, in 2027, the 49ers are projected to be $35.1 million over the cap, then over by $20.4 million in 2028.
That cap space will have to come from somewhere. And a lot of it might be from a grim resolution.
49ers may need to soon part with Christian McCaffrey to land Vita Vea
Salary-cap gymnastics are certainly a thing, and the Niners have done this well over the years. Heck, one argument why they're not currently using their cap space is so they can roll it over into 2027, thereby eliminating the $35.1 million overage.
But Vea is likely to ask for something in the range of $35 million to $40 million per year, boosted by the Philadelphia Eagles extending defensive tackle Jalen Carter on a league-setting $152 million extension.
One way San Francisco could absorb that kind of extension would be to finally pull the plug on their reliance on McCaffrey, the All-Pro who effectively makes head coach Kyle Shanahan's offense tick.
As difficult as that might seem, it does make sense, both from an age/health perspective and financially.
Perhaps Vita Vea forces 49ers to have tough Christian McCaffrey conversation
McCaffrey just turned 30 years old and is coming off a 2025 campaign in which he led the NFL with 413 touches. Historically, both with the 49ers and Carolina Panthers, CMC has struggled to stay healthy in seasons after massive overuse, meaning 2026 is already in danger.
Even if McCaffrey stays healthy this season, he's already beyond the point when most tailbacks call it a career, thanks to the wear and tear on their bodies.
Looking at things financially, McCaffrey's current contract expires after 2027. But he's also run out of guaranteed money on his deal, too, meaning it'd be easier for the Niners to get out from under his services than it would've been a year or two ago.
With a post-June 1 designation, San Francisco could release McCaffrey in the spring of 2027 to free up $17.5 million of much-needed cap space, albeit against $8.9 million in dead money.
Along with some other cap-related maneuvers, that $17.5 million would go a long way toward meeting Vea's contractual demands.
Even if it'd be a tough pill for 49ers fans to swallow, although they're already being forced to come to terms with McCaffrey's Niners career winding to a close.
