What the team have achieved so far this season is part of what any prospective FA will think about. But it won't carry as much weight as; contract money, who else is signing and how good the coach is looking. Not his personal appearance, as a NBA coach.
It certainly could be something that sways a FA our way as the players obviously enjoy playing in Boston and play for each other. Despite the weather, night life arguments etc I think we need to use what we have to attract at least two FAs. Half the season is spent in other cities anyway and nobody says that because you play for a team it will be where you settle forever.
I think we have a good opportunity to attract someone.
