I think if we have a starting unit of:
IT
Brown
Hayward
Morris
Horford
And then bring in off the bench, in order, Smart, Baynes, Crowder, Tatum, Rozier and make the substitution pattern such that either IT or Gordon or both are on the court at all times. We will be a slightly better defensive team than last year and much better offensive team.
Unfortunately, unless Horford, Morris, Hayward and Brown can all average above 6 rebounds a game while getting 5 a game from Baynes, we are once again going to get killed on the boards.
