The Donovan Jennings get is a good one. Basically like another R7 pick with the guaranteed money, and probably a better fit than their R6 pick Glover. There's twitter cutups of him holding up to Dallas Turner pretty well.
He'll get a legit shot to make the roster as a backup G-T. Don't know much about the others, although I hear the LS has a decent shot of unseating Orzech.

With all the draft picks they've had in the last 3 years, there aren't a lot of spots for UDFAs left.
Feels like a young roster that is divesting a lot of bloated/cap hell contracts.
