Hopefully we find a diamond in the rough with the pick.
You love to do that to people, don't you?
First, the pick is likely going to NOP, but pick #13 is still a lottery pick and even recently produced Donovan Mitchell and Devin Booker. I agree it isn't where we all hoped, but it's not like pick #47 or anything. Diamond in the rough...classic LB 
the last 5 drafts these are the players drafted from 12-15
2018 - Miles Bridges, Jerome Robinson, Michael Porter, Troy Brown
2017 - Luke Kennard, Donovan Mitchell, Bam Adebayo, Justin Jackson
2016 - Taurean Prince, Georgios Papgiannis, Denzel Valentine, Juan Hernangomez
2015 - Trey Lyles, Devin Booker, Cameron Payne, Kelly Oubre
2014 - Dario Saric, Zach LaVine, TJ Warren, Adreian Payne
Aside from Mitchell and Booker, it looks like pretty much a crap shoot.
