Technically the Browns could allow Mack to go for the $18m over two years that the Jags have proposed but there are so many reason why the Browns need their veteran center.
At the moment, the only quarterbacks on the Brown's roster are named Alex Tanney and Brian Hoyer with a combined 18 NFL starts between them.
That is not the problem that it needs to be with a deep draft class and a lot of Browns picks. Cleveland also have the blessing of a competent offensive line, centred around Mack.
However, if the Browns allow Mack to join the Jags; they will have no quarterback, no protection and quite frankly then it wouldn't matter how good Josh Gordon is, they are not winning many football games.
The Browns have the money to spend too, $30.7 million in cap room according to overthecap.com . Browns management have made the right noises regarding the deal and I do fully expect them to match the deal but this would not be the first time that Cleveland do something unexpected and potentially devastating.
The Jaguars have made great strides this offseason and securing this Mack coup along with the capture of a new quarterback would pretty much put the cherry on top.
The Browns have not been terrible this offseason but a lot of their work is still to be done. If they were to allow Mack to disappear pre-draft it would make a difficult job very close to impossible for the Browns organization.
