Jalen Mills, S/CB (4 years, $24M) The Patriots opted to switch Mills to cornerback this fall in the absence of Stephon Gilmore, and so far, it's been ugly. Working opposite J.C. Jackson, Mills has been targeted early and often through five games played, allowing completions on 15-of-24 attempts for 190 yards and two touchdowns.
