I don't have a full understanding of it, but apparently these UDFA base salary guarantees to transfer over as a split salary if they're cut and re-sign to the PS. Definitely shows how much a player is liked but obviously, guarantees them nothing in terms of a roster spot.
im more looking at the signing bonus - there's only so much money allotted to give out to the udfas - and i think it's only been around 100k
which means giving a guy over 10k of a bonus is a pretty decent commitment to a udfa - we clearly wanted him enough to offer him a tenth of our bonus allocation
