I had a S3 in MFN-7 last Season, this year I'm only rocking 4 CB and 2 S total. I'm not expecting to much of an issue here (I traded my Starting FS and had cut a Back Up S Pre-Draft who wasn't that good).

Notice how my RDE2, LDE2 and DT3 are the same guy. Baker and Grooms will get maybe 20 snaps all Season... combined.
At LB, K. Scott likely won't see 25 Plays total, more likely Less than 10 (unless Injury, of course).
It's really about how comfortable you are with Injury Risk.
