With Browns rookies due to report to Berea on Friday, the team and first-round pick Barkevious Mingo are still at odds over his contract, a league source told The Plain Dealer.

Specifically, the Browns want offset language in the deal, and Mingo's side does not. Offset language addresses a player who is released before his fully-guaranteed four-year contract has expired. With such language, the original team only has to pay the difference between what it owed the player and what he'll make from a new team.

With no offset language, the player receives the full amount from his original team and a new team.

Mingo, the No. 6 overall pick out of Louisiana State, is one of three unsigned Browns draft picks. The other two are third-round pick Leon McFadden, a cornerback out of San Diego State, and seventh-round pick Armonty Bryant, a defensive lineman out of East Central University.

The Browns are confident that all three will be in on time, according to a source. But "on time'' at least in Mingo's case might mean when the full squad takes the field for the start of training camp July 25.

Mingo, who worked with the second team during minicamp, is set to make slightly more than his former LSU teammate, cornerback Morris Claiborne, received from the Cowboys last season. Claiborne, the sixth pick in 2012, received a fully-guaranteed four-year deal worth a total of $16.26 million, including a $10.3 million signing bonus. He does not have offset language.

So far, only three of this year's top 10 picks have signed, and none have offset language in their contracts. They are No. 2 pick Luke Joeckel of the Jaguars (four years, $21.2 million), No. 5 pick Ziggy Ansah of the Lions (five years, estimated $18.6 million) and No. 8 pick Tavon Austin of the Rams (four year, $12.751 million).

Last year, only one of the top nine players had offset language in his contract -- Miami QB Ryan Tannehill.
