Glover Quin's reworked deal gives Lions more cap space

Detroit Lions safety Glover Quin has tweaked his contract, converting $3.255 million of his 2015 base salary into a signing bonus, creating $2.17 million of cap space for Detroit while ensuring himself more guaranteed money sooner, per a league source.

Quin was originally scheduled to make $4 million in base salary for 2015, none of which was guaranteed, and his new base salary for 2015 is $745,000, while his cap number is now $3,572,500. It's the second time that Quin has restructured his deal in less than nine months, as he assisted the cap-needy Lions just prior to the start of the 2014 regular season.

While the productive safety's base salary for the 2016 and 2017 seasons remains unchanged, his salary-cap charge will rise by $1.085 million over each of those seasons. His cap charge for 2016 is now $7,577,500 and his 2017 cap charge is now $7,827,500.

When Quin initially signed with the Lions in 2013, the deal included $7.25 million in guaranteed money. In executing the two separate renegotiations, that figure has escalated to $12.005 million.

The former 2009 fourth-round pick has emerged as one of the league's most productive safeties, as he has 10 interceptions during his first two seasons in Detroit after spending the first four years of his career in Houston.

The move creates a bit of breathing room for the Lions, who remain tight against the cap this offseason.
