The Browns are trying to trade offensive lineman Cameron Erving, a league source tells Mary Kay Cabot of Cleveland.com. Erving, a former first-round pick, has lost the starting right tackle job to Shon Coleman, so he is too expensive for a backup role and therefore expendable.

Erving was competing for the No. 1 right tackle job before suffering a calf injury last week. Even though the battle was ostensibly close, Erving’s salary is significantly higher than that of Coleman, a third-round pick in the 2016 draft. If possible, the rebuilding Browns would like to take Erving’s salary off the books and get some draft capital in return.
The former Florida State standout is due to carry a cap hit of $2.571MM this year and $3MM in 2018. He has yet to put it all together at the NFL level, but he does offer versatility, including the ability to play center.
Erving isn’t the only Browns player on the block. The team is aggressively working to trade cornerback Joe Haden and quarterback Brock Osweiler is said to be available.
Cleveland and Miami should have a chat. Erving and Haden for Landry and Maxwell, maybe some mid draft pick swaps if the value is off.
I like your idea except for trading Landry
Erving to Jags.
They need OL help and salary is not an issue.
I would think they could put Erving at C and move Linder back to G.
