Somewhat realistic? Cut Hyde. Trade Jack.

Figure out Little's place on the line. Once you do that, target either LT or RT. That may be offering Cam a long-term deal, it may be a different FA. Regardless, replace Taylor.
Bring in a good RB. Etienne and JRob both are coming back from significant injury. We have no guarantee of their recovery to prior form or their sustained durability. Can't have too many RB, as we've seen, injury is likely to deplete the depth over the course of 18 weeks.
Get a MLB who is going to run your D. Jack was terribly miscast, Scho was traded for peanuts, and Wilson has been serviceable at best.
Get a WR who is going to be TLaw's go-to guy for duration of each player's career.
It's time to move on from Linder/Shatley, bring in their replacement. This may be week 1 replacement or a gradual development over the season.

Not gonna pose specific names, because there's a number of guys that can fill those roles, whether by FA or the darft. Those are the priorities. Take care of those, and the rest of the moves will take care of themselves.
