2. Stephon Gilmore
It hasn't taken Stephon Gilmore long to become a Dallas fan favorite.
The veteran cornerback was acquired from the Indianapolis Colts during the offseason and has lived up to expectations since then. Through 6 games, Gilmore ranks second on the Cowboys in solo tackles (20), interceptions (2), and defended passes (6).
That's without mentioning how he's also allowing a measly 52.2% completion percentage and 51.7 passer rate when targeted.
Is Gilmore still at a Defensive Player of the Year level? Maybe not, but he's done more than enough to solidify himself as a key piece in Dallas' secondary. It's a good thing he's done so, too, considering how fellow CB Trevon Diggs is out for the year with a torn ACL.
At the end of the day, 6 games with a new team might be a small sample size for an extension, but Gilmore is a known commodity at this point. He hasn't been noticeably declining yet, so as long as he keeps his current level of play going I wouldn't mind seeing him stick around for a few more seasons.
