Cleveland Browns center Alex Mack voided the three years remaining on his contract and will reportedly become a free agent, according to ESPN's Adam Schefter.

Browns C Alex Mack is voiding the 3 years remaining on his contract and is set to become a free agent, per source. One more free agent OL.

Mack's current contract would have paid him $24 million over the next three years, but he has just the fourth-highest average salary among centers in the NFL, trailing Maurkice Pouncey ($8.83 million), Rodney Hudson ($8.90 million), and Mike Pouncey ($8.95 million).

If the Jaguars (or any team) want to sign Mack next week in free agency, they will likely have to average at least $9 million per year. With the most cap space in the league and the most rollover from last year, will the Jaguars dedicate 10-15% of their available cap room to a center, even if he's the best center available?
