It's trade deadline rumor season and Ainge has already thrown some cold water on the odds of the Celtics making a trade, but add a new name to the list in Danilo Gallinari. The Thunder stretch 4 is attracting interest from several teams including your Boston Celtics who are "monitoring" the situation.
While Danilo Gallinari of the Oklahoma City Thunder isn't a power player, he's a legitimate scorer at 6'10", and he's another guy Boston has monitored, per an NBA source.
It's unclear if the Celtics are going to trigger a deal, but Drummond and Gallinari are not inexpensive players, and Boston isn't likely to afford both when landing one will take significant outgoing salary.
