Hettiger isn't going to sign for $125k.
I have to figure Miller signs for something near slot. Maybe a bit more. He has a real option in Arkansas. $3 million?
Reports seem to be that Saltiban wants to sign, and U. Hawaii isn't an SEC-caliber program. He was drafted ahead of his ranking, so... $650k? A bit under slot.
Walton? He's committed to Miami, which is something, but he, too, was a bit of an overdraft...$500k (i.e., slot)?
Miller might need more than I'm guessing, but I don't see Saltiban and Walton eating into the money available for Hettiger very much, and we may see some minor pool savings there.
Not wanting to be negative or critical, but I'm kinda coming to the conclusion that the Gelb comment there was a bit of a throwaway - i.e., "they drafted a bunch of college players in rounds 6-20 to save money for the top three," without really focusing on the three players actual signability.
