They were saying all this about Denver, even just 3 months ago. Denver couldn't win in the playoffs, regular season team only, soft on defense, and so on. A lot has to go right to win a title. All this is true until it isn't true. I don't know if this Celtics core will win a title or not, but I think they are going to. This is a very young core. Other than Magic Johnson winning a title his rookie year, most players or core teams take a few tries before they win it all.
Ime did not get the team over the top in his one season run at it, and he had everything the way it is supposed to be. Hired as coach in the summer, bring in the assistants you want. Get everything ready for the start of preseason.... Last season, Mazzulla was thrust into the role after a scandal, very late in the off season, worked with inherited assistants.... I think all of this did lead to some team or chemistry issues.
This team looks really good this season. I think it is premature to come to any conclusions about how unserious they are or will be this season. I have been critical of Tatum at times about posing after shots and that kind of thing. Not sure if that is part of the unseriousness. For the most part though, this team plays hard and I think will be very serious about winning a title this season. It is no given though, winning a title is a long physical and emotional marathon.
