I'm not Russ Ball or Gute, so its hard to know what they are thinking in regards to the cap, resigning of our own guys between now and next year and FA's. If Gute is still looking for additions to the current roster, I can't imagine they want to sign more than one "big contract", unless they are willing to cut ties with someone like Bulaga, Cobb or Matthews.
So where would you splash that "big" money? I would think OLB or WR, if someone is there that you want longer than a year.
Otherwise, you look for a few guys like Kendricks that improve your 2018 roster and a smaller cost. Players that are a lot like Mo Wilkerson, a player that might be willing to play relatively cheap on a one year deal to reestablish their market value.
