I wouldn't be opposed to bring any of them back actually, except for Sheldon. The guy showed up lame on the biggest stage, something surprising for a guy from Duke, although it's been awhile.
Scal is the best cheerleader in the world, is good for the locker room, can hit an open three (if it's not windy) and hustles every second he's on the court.
Finley is a knock down shooter (from downtown and mid-range), who is an underrated rebounder and better defender than people give him credit for. Players like this may not get much PT in the playoffs, but they can help a team during a long season.
Daniels got the shaft after his injury. I don't know why, but he could never get the PT or on a roll when he got some time. He looks like he can do everything effectively on the court. Will he take a discount with us two years in a row when the first season was a complete failure?
None would be expensive, and all could be had for two years (or less).
