Nah, I think they wanted to have the flexibility to look at a D-Leaguer or two and then at the end of the regular season, like they've done in recent seasons, they'll settle on a veteran wing (unless Green blows them away) for insurance purposes.
With Daye, clearly they wanted to see if he could be Bonner's replacement. They obviously came to the conclusion that he couldn't, so at this point, he was just filler. Besides, two non athletic forwards, with no true defensive position, is poor use of roster space, especially for the team that values every last spot more than any other.
