In light of the Kevin Garnett trade to Celtics, what other players should Celtics get to make team complete?

Linas Kleiza would be a great defender to help out with the Celtics defense.Calvin Booth is an offensive center with the ability to work it inside the paint and score. Boston is also lacking the PG position, so I would say Brevin Knight could do wonders for the offensive game, he's not much on scoring but the man picks defense apart with persision ping. I was thinking about a forward for the Rockets named Steve Novak. I watched him play last year, he would fit nicely with the team in green.
