Patriots, Gronkowski agree to 2017 incentive package

Last year, the Patriots and tight end Rob Gronkowski began the process of negotiating a new contract. Instead, it’s simply more money based on performance, on top of the money Gronkowski already was due to earn. Gronkowski had been due to make $5.25 million in 2017, roughly $8.5 million in 2018, and $9 million in 2019.
