The Miami Dolphins have agreed to a historic deal with Xavien Howard.

The five-year deal is worth $50.6 million in new money and gives Howard the most guaranteed cash for a cornerback in NFL history.

Howard had three years and $39 million remaining on the five-year, $75 million contract he signed in 2020 but had grown discontent with the deal entering the 2021 season. 

The 2016 second-round pick requested a trade in July, saying he didn't feel "valued or respected" by the organization that drafted him.
