This isn't that kind of draft bruh... The talent gap from #2-#8 really isn't that wide... There's isn't even a consensus #1 that should tell you how these guys are being viewedIn a trade down, sure, but at #2 with a gaping hole at center and a sure fire guard next year, they should address the best way they can have some size on the court.
Secondly I just don't think the Warriors value the center position like that...it's not like they run plays for their bigs... They probably feel like they can get a ring chaser to take a paycut to start at C (Marc Gasol/Aron Baynes/Robin Lopez/Howard) will all be available
