Source says Iowa State F Royce White does not have a promise from Boston.— Sam Amick (@sam_amick) June 22, 2012
NBA source said Celtics don't make promises: "They're out of promise game." Also said 21 is too late for a promise.— Dan Duggan (@DDuggan21) June 22, 2012
However, Jay King of Celtics Town appears to have a source that backs up Chad Ford's original story.
The concept still seems odd to me, promising to select a prospect late in the first round despite not knowing who will remain available at that point during one of the deepest drafts in years. But a source with knowledge of the situation told me today that the Boston Celtics indeed have made a draft promise to Royce White, as first reported by ESPN’s Chad Ford. The source told me that the Atlanta Hawks also have expressed interest in White, a 6-foot-8 power forward from Iowa State, but are "operating under the assumption" that Boston has every intention of taking him with either the 21st or 22nd pick.
Promise or no promise, the kid seems like a good pick to me.
