I read somewhere that the Thunder have re-hired Rob Hennigan as Assistant GM, and it made me want take a look in to his draft history and transactions over his 5.5 year run in Orlando.
2012 1 19 Andrew Nicholson
2012 2 49 Kyle O'Quinn
2013 1 2 Victor Oladipo
2013 2 51 Romero Osby
2014 1 4 Aaron Gordon
2014 1 12 Dario Šarić
2015 1 5 Mario Hezonja
2015 2 51 Tyler Harvey
2016 1 11 Domantas Sabonis
2016 2 41 Stephen Zimmerman
2016 2 47 Jake Layman
Drafting is a crap shoot and everyone misses, but Oladipo, Gordon, Saric, and Sabonis is a very promising team. Consider that they also had Mo Harkless, Tobias Harris, E'Twaun Moore and Nikola Vucevic as either 1st or 2nd year players when Hennigan took over, and that is kind of a good set of players to work with toward rebuilding.
Of course if Hennigan isn't making trades to stunt their team, they may not be in position to have all of those players. Mostly I wanted to focus on the fact that, while Hennigan is an okay drafter, he just happened to be really terrible at everything else.
Guys like Danny Ainge are rare. He has an above average drafting record and a nearly unimpeachable trade history, in addition to hiring great coaches and staff (Zarren shoutout!).
