Let's say pick 29 is about to be on the clock. So far, you've caught no breaks. E.g.:
Aaron Donald is a Cowboy.
Ra'Shede Hageman is a Raven.
Ryan Shazier is a Packer.
Dee Ford is a Saint.
Absolutely everybody is trying to trade down for more picks, so you can't find a trading partner. (An all-too-realistic possibility, according to current chatter.)
Who is your fallback plan, the player who you feel pretty confident will be available at #29 if you have to take them?
I am guessing Nix would be long gone at this point and Ealy is also most likely off the board. If this were the case then I would go with Moseley as LB is the most pressing need to me and Mosely is a great prospect with experience in a pro style defense. Basically my top prospects for the pick are gone so this really would be the fail safe pick.
