The team as constructed, is better. I don't think it is a great deal better, but, this group is an improvement.
To exploit Horford's talents, the team's tactics didn't fully exploit the rest of the player's strengths.
The Cavs aren't very good, but, they aren't that bad. The Cav's and others have no answer for this team's "spread" on offense and commitment to defense.
If Stevens gets this right, this team will elevate past their front court weakness, which includes the loss of Horford, and play the full tilt athleticism card.
I think it was their second regular season game this year, this team got caught "chucking" one after the other from the perimeter. That was the last time I remember screaming at the TV to "go inside". They all go inside now with great effect.
This year's team has a lethal balance of inside and outside from all four of their stars. I suppose, Horford's departure, unintentionally, set them free.
