I'm mostly naive but skeptical that a 6-9, 175 PF is the 3rd big this team needs. That's Evans.
Paying attention to Jeff Withey for that role (or 4th big, since I still am holding out hope the Jazz can retain Millsap).
Withey wouldn't be a bad choice with the GSW pick (assuming 20'ish). Willie Cauley-Stein is one to watch there as well. Legit 7' that played wide receiver and is the fastest guy on UK's team .. blk per minute are off the charts, great hands, athletic as hell.. either of them. Withey more refined at this point, with WCS having more upside, imo.
