Contract extensions before the season starts

Loomis has been really quiet and we have some big UFA and RFA for next year. Drew, Vaccaro, and Snead all will have huge roles this year. I know Drew is pretty much a nonfactor (although he does carry the signing bonus hit til 2020).. but are you guys concerned with us not locking Kenny up yet? He's the veteran leader of the secondary and will be a UFA. His role is literally everywhere on defense. Should we lock him up before the season or run the risk of him playing out of his mind then testing the market/driving the price up?

Same with Snead. He's the clear WR2 and should break 1000 yards for the 1st time with Cooks gone. With a good season, he'll get interest as a RFA. Wouldn't it be to our advantage to extend him before he sees his biggest production yet?

Any news or updates on the matter? We do have the cap space to make something happen
