Defense Stash

Is it worth stashing 2 Defenses for week 15 and hopefully week 16 championship?

Currently have a bye and have Baltimore for week 15 at home against TB.

Thinking of dropping Coleman or C Davis and stashing Denver for week 16. Have good depth at RB and WR.

Question: Drop Baltimore for Denver for week 15/16 or stash Denver for week 16 and drop a Coleman or C Davis??

Roster multiple Ds.
