Decent three-point shooter, and likely the best available guard on the market. Was caught in the numbers game in Atlanta.
Was also on an active roster this season, which is not to be ignored where game shape is concerned.
He should be on the next flight to Boston.
edit: The problem he just finished his second 10-day stint with Atlanta, and since he's played well my guess is they'll keep him until the end of season. So he's likely unavailable.
