Boston has the right to swap its 2017 1st round pick for Brooklyn's 2017 1st round pick; if Boston exercises this swap right, then Boston will convey its 2017 2nd round pick to Brooklyn protected for selections 31-45 (if this pick falls within its protected range and is therefore not conveyed, then Boston's obligation to Brooklyn will be extinguished) [Boston-Brooklyn, 7/12/2013]; this potential pick conveyance is the same as the one described in "2017 second round draft pick from Boston" on Brooklyn Incoming

So basically we have the right to swap with Brooklyn which we will do and 3 second rounders this year. 2 first rounders in 2018 and potentially 3 more 1st round picks coming in 2019 which could parlay over into something better.
The C's are loaded with lottery implications the next 5 years or so. The two big ones being the brooklyn picks the next couple.
Nothing overly new here. Last year we were loaded with picks, but still have a lot more coming!
