Having the top pick doesn't guarantee you the best player. This is not a draft where there is a lebron james or Kevin Durant. This draft to me is close on talent of the 2010 draft. So many good players in top 10. There have not been many drafts in the last 10 years that have generational talents. Most of the drafts the best player was not picked at 1. This draft is just the same. No generational talent but deep. The best player will most likely not be Fultz. Danny knows this. Brad knows this. Next year has that potential to have multiple generational talent type players and that is why this move was made. I trust the scouting of the celtics and if they feel the best player is not Fultz and they can walk away with the best player in this draft and a future asset they I trust them. They could be wrong but if you look below a lot of teams were with the picks they made.
2009 - Blake 1, Harden 3, Curry 7

2011 - Kyrie 1, dwill 2, kanter 3, klay 11, kawai 15, jimmy butler 30. Kawai is the best in the draft with Klay and Jimmy Butler close to Kyrie
