Just as DE Jared Allen has generated little interest, Alex Mack is one of the best centers in the league but there's no interest in him so far in free agency. But the black scrubs, has-beens and never-weres continue to get signed left and right. Profootballtalk reports free agent C Alex Mack hasn't taken any visits and is generating no interest. As Mike Florio points out, it might be best for Mack to sign the one-year, $10.039 million transition tender the Browns slapped him with before GM Ray Farmer rescinds the offer. The money around the league is starting to dry up one week into free agency, so the chances of Mack landing a deal he likes appear slim. He can earn the hefty salary in 2014 and hit the open market again next March.
