If Celtics are able to reduce their extreme dependence on 3 pointer shots, and find other ways like driving into perimiter more and geting more point from the paint area, they'll be a team to be in the league this season and I'll tip them as my favorite for the championship this year, provided they are able to keep their core players fit and avoid long term injuries that could deter their ambitions.
Honestly, they really have a high chance of winning the championship this year but we all know because of how different regular season games are from the playoffs, anything could happen especially when they suddenly lose a player due to major injuries but right now obviously, that's not the case anymore because of their strong bench players as well and their team seems to be leading the NBA throughout the season because of this and they are more likely be winning the championship as well if they can always play such high-level chemistries and skills.
