Supposedly, the Patriots offered Butler 3 years/18-20 million last summer. That breaks down to
2016: 6 million - He made $600,000
2017: 6 million - Tender is 3.91 million
2018: 7 million - He'll be unrestricted, so in order to recoup the money he could have signed for, he'll need to be paid 14.5 million
Derek Simpson, the ambulance chaser lawyer that is his agent, turned it down, maintaining his client should be paid as a top CB on the market. As a result, the Patriots ended negotiation of any extension, having tired of Simpson's antics and refusal to negotiate in good faith.
