Call or fold?
According to ESPN’s Adam Schefter, the offer is for $42 million over five years, and Mack will receive $26 million guaranteed.
The Browns have five days to decide whether to match the offer or to allow Mack, who received the transition tag from Cleveland, to sign with Jacksonville.
The Browns will not receive any compensation should they allow Mack to depart.
The 28-year-old Mack has played and started all 80 regular-season games for Cleveland, which took him in the first round in 2009.
The Jaguars’ interest in Mack pits two rebuilding clubs with a good deal of salary cap space. Now, the focus turns how the Browns play their hand.
