In case you missed it, here's a piece on Suhs contract. The key information is this:
According to Spotrac, the Dolphins are more than $7 million over the cap for the 2016 season right now. A large part of the reason for that is Suh's $28 million cap hit, which includes a base salary of $23,485,000. That base salary is a massive jump from last year's base of just $985,000, which the Dolphins made that low so they could fit him onto last year's payroll.
