Joe Douglas has a lot on his plate this offseason.

But priority No. 1 has to be helping quarterback Sam Darnold find success – fast. That means bolstering the offensive line, for sure. It doesn’t really much matter how good Darnold’s weapons are if he doesn’t have any time to find them.

Left tackle Kelvin Beachum is a pending free agent. So is center Ryan Kalil. Also right tackle Brandon Shell. Right guard Brian Winters can be cut without any penalty. In other words, it’ll be easy for Douglas to clear spots up front in order to make way for new talent.

Now comes the hard part: Finding the right pieces.

So, who are Douglas’ best options in free agency, as he tries to give Darnold the best protection possible? Here are the six best choices expected to hit the market:

G Brandon Scherff, Redskins

Sure, the Redskins have been terrible for a while – but Scherff has been one of the few bright spots. The only question is whether the 28-year-old can stay on the field consistently. He was healthy for his first three NFL seasons, but played just 19 games over the past two years. That’s a potential cause for concern.

OT Anthony Castonzo, Colts

Castonzo’s age, at least at first glance, may feel like an issue. But the 31-year-old just had arguably his best of nine NFL seasons in 2019. He’s probably still not worth a massive long-term investment, but a well-paid short-term deal could strike a nice balance for both sides.

OT Jack Conklin, Titans

The 25-year-old had a tough time against the Chiefs in the AFC title game, taking a pair of penalties. But he’s still probably the most impressive option on the market, given his position on the exterior and his youth. It’s not super often that an offensive lineman of this caliber hits free agency right in the prime of his career. He could command quite a price tag to become someone’s right tackle.

G Joe Thuney, Patriots

The best part of potentially signing Thuney for the Jets? It kills two birds with one stone. Suddenly, they’d be adding a skilled interior linemen, while also stealing one of the Patriots’ best performers up front. That kind of shift could be helpful in dismantling the dynasty – though the Jets still have plenty of other work to do on that front, too, of course.

OT Bryan Bulaga, Packers

Bulaga has a lot of tread on the tires – but also an impressive amount of experience. The right tackle has played 10 seasons by age 30, which is impressive all on its own. He’s only started all 16 games twice during that span, though, so injuries a real concern to weigh against his wealth of talent.

OT D.J. Humphries, Cardinals

There are some solid tackle options on the market, but most of the best ones play on the right side. Humphries is one of the few exceptions who could lock down Darnold’s blindside. He may not be the prototypical No. 24 overall pick, but the five-year veteran had a strong 2019 campaign after battling through injuries over the previous two seasons. He’s set up for a payday now, given the premium put on his position.
