Jalen Mills, CB, New England Patriots
Dallas had one of the top defensive backfields when they took the field in Week 1 with Stephon Gilmore joining Trevon Diggs. In addition to those two on the boundaries, they had DaRon Bland playing the slot corner.
There's also a trio of safeties with Malik Hooker, Jayron Kearse, and Donovan Wilson all doing their part. They even had so much talent at safety that Dan Quinn moved Markquese Bell to linebacker, where he's been thriving.
Unfortunately, the secondary wound up taking a hit when Diggs was lost for the season due to a torn ACL suffered in practice. Jourdan Lewis stepped in and became the No. 3 guy while Bland moved to the outside but they haven't been the same. That's why targeting a defensive back makes a lot of sense.
One player who could be available is Jalen Mills, currently on the New England Patriots. Mills signed a one-year deal in the offseason, making him a free agent at the end of the year. With New England sitting at 2-5, they might be willing to move on and look for future assets in return.
One reason Mills makes sense is his versatility. As mentioned previously, Quinn has no problem moving his defenders around and Mills has played both safety and cornerback throughout his career.
Being able to move him around based on matchups while also providing someone who can cover deep from the free safety spot is a weapon he would surely love to add.
