With the deadline for signing an offer sheet with a new team coming in four days, Giants cornerback Kevin Dockery has opted to take himself off the market.

The one-year, $1.545 million contract means that Dockery will remain with the team for at least another year.

The Giants had tendered Dockery at the second-round level.  Not bad for an undrafted free agent who has 40 regular-season appearances and seven starts during his three-year career.

 

The importance of this move is dictated by what we do in the draft. Dockery is a decent to average #3 CB, but a great number four CB.

 

I think if the Giants get a good value on a safety prospect early they might take one and let Terrell Thomas stay as the nickel CB.
I think if the Giants move Terrell Thomas to Safety then they should definitely grab a Cornerback, because I don’t love Dockery as a number 3 Cornerback. He’s solid, just not spectacular (that’s not really a knock, being a solid NFL player is a good thing).

In either case, you can never have too much depth in the secondary (especially with the nagging injuries Aaron Ross always has).
