CLEVELAND, Ohio -- The Browns' play at offensive line improved late in the 2018 season, particularly with the move to Freddie Kitchens at offensive coordinator.

Former No. 2 overall draft pick Greg Robinson also helped the improvement after taking over at left tackle for undrafted rookie Desmond Harrison. Robinson is a free agent this offseason, but is he a longterm solution?

Following last week's look at the top 50 free agents and then some, here is a deeper dive into one of the Browns' positional needs: Offensive tackle.

The Browns are projected to have nearly $75 million in cap space, according to Spotrac.com, ranking them with the fourth-most available cash in the league. Only Indianapolis, the New York Jets and Buffalo are projected to have more.

Here are the best options at offensive tackle, ordered by how expensive they were in 2018 and starting with the cheapest.

Trent Brown, New England

PFF rating: 66.9

2018 cap hit: $1.9 million

Age: 26

Brown might be the best option at tackle in the free-agent market. The Patriots shouldn't be so cap strapped that they can't keep him, but teams such as the Browns should be able to lure him with their finances if they desire.

Daryl Williams, Carolina

PFF rating: 64.9

2018 cap hit: $2.0 million

Age: 27

Ty Nsekhe, Washington

The Bengals did not pick up their fifth-year option on Ogbuehi, who started two games and appeared in just four in 2018, struggling in the preseason and falling out of favor. The Bengals even brought back former first-round pick Andre Smith at tackle. Coincidentally, they also spent a first-round pick on Ogbuehi. Smith and Jake Fisher also are tackles from Cincinnati who are available this offseason.

Seantrel Henderson, Houston

PFF rating: 63.3

2018 cap hit: $3.2 million

Age: 27

Henderson might be best remembered for being a highly touted prospect from Minnesota who signed with the University of Miami.
