Our defense will be bottom 10 if hayward or tatum start at pf.
Well, depends on the rest of the team, but with a qualify defensive 5 like Adams and two good defensive guards like Smart/Brown? That would be a very good NBA defense I think. I should think the offense would be their achilles heel.
Heck, last season Horford played 5 most of the time - Baynes only played ~800 minutes and few of those along Horford. Most of the lineups had Hayward/Tatum/Morris at the 4. And the team still had the 7th best defense in the league - in spite of a weaker defender like Irving at the 1. Do you think Morris is a much better defender than Hayward/Tatum at the 4?
Here are the best defensive 5-men lineups for Boston last season among those used at least 50 minutes. At bold, the two forwards (3 and 4):
A. Horford,
G. Hayward, .K. Irving,
M. Morris, M. Smart
D. Theis,
G. Hayward, T. Rozier, J. Brown,

That said, I'm not convinced that absorbing Adams contract is the way to go.
