Let me start this off:
I'm more or less okay with any pick, as I don't expect any player to contribute next year, which I view as the last year of the "window".
I can see the justification for a big man with upside (e.g.: Jeremy Tyler), or a young college player with, arguably, a ton of upside (e.g.: Tyler Honeycutt) or for a college tested player who delivered but wasn't as spectacular as players who were picked in the lottery (e.g.: Reggie Jackson).
Where I have a hard time is with players like Marshon Brooks, who were unspectacular, but then had one good year, and whose skill (aka "volume shooting") might not transfer well to the NBA.
So I guess I'm picking Marshon Brooks.
