take it for what its worth

TE Rob Gronkowski ($8,650,000 cap charge) – Gronk must stay healthy the rest of the 2014 season in order to remain worthy of such a high cap charge. Otherwise, I could see the Pats releasing him before the start of the 2015 League Year so as to avoid guaranteeing his 2015 $4.75 million salary. -

Gronkowski is set to make $15 million alone in 2015, in the form of $5 million in salary (which is guaranteed only for injury but not for cap or production purposes), as well as a $10 million option bonus that the Patriots could opt to pick up at any point in the 2015 league year. Numerous sources who reviewed this contract said they highly doubt New England picks up that $10 million option, which would make Gronk a free agent.
