The 2013 3rd rounder puts it over the top for me.

It wouldn't work in terms of matching salaries, but theoretically I'd do that if 1) Howard's agent said he'd sign in Boston to play with Dirk and Rondo, and 2) it left us with enough cap room to pull that off (I haven't checked, but I assume it would).
If Dirk would help us restart the rebuild, fantastic. If not, I'd rather keep Pierce in green.
