Looking at the current Celtics roster from ESPN - it appears the Celtics lack height and have too many wing/guard players.
https://www.espn.com/nba/team/roster/_/name/bos/boston-celticsJaylen Brown 6'6"
*Kris Dunn 6'3"
Carsen Edwards 5'11"
*Bruno Fernando 6'9"
Al Horford 6'9"
Enes Kanter 6'10"
*Luke Kornet 7'2"
Romeo Langford 6'4"
Aaron Nesmith 6'6"
Jabari Parker 6'8"
Payton Pritchard 6'2"
Josh Richardson 6'5"
Marcus Smart 6'3"
Jayson Tatum 6'8"
Grant Williams 6'6"
Robert Williams III 6'8"
Sam Hauser 6'8" two way
*Yam Madar 6'3" ??
The asterisks are for players I'm not sure if they are officially on the roster or are questionable if they'll be on the team.
R Williams plays much taller than 6'8", but is injury prone.
Al is getting up there in age - who knows how he'll hold up this year. Just pray he comes into camp in shape.
It looks like the team will have trouble rebounding, blocking shots and clogging the lane. There's little intimidation factor.
I was hoping Moses was going to stay - he keeps penetrating guards wary around the hoop. R Williams does that too. Just he's not on the court all the time.
Overall, it looks like we have too many guards/wings and not enough athleticism on the boards and defensively against bigs.
