The nice thing about this upcoming draft is that the lottery teams competing with the Brooklyn pick (Philly, LA, Phoenix, New Orleans, Sacramento) have all recently devoted assets to the PF/C positions. All could use a good SG/SF, which is an area of strength among our young players. There are a bunch of pgs coming out early, and I could see many of the same teams picking one.
Therefore, the Celtics (with any luck of the ping pong balls) will have a decent chance at picking either the best or 2nd best big man in the draft.
