Ed Davis also has a chance to be a double-double player, but he's got a very high basketball IQ, is a smart defender and is renowned for being a hard worker. No one has ever questioned Davis' focus or ability to understand plays. I'll take Davis over Hickson at this point and I'd venture a guess that most GMs would do the same thing.
And Davis' father is a former NBA player who kicked around the league for 10 years because he was a grinder. Having a father who played in the league, and wasn't a dick, must be a great resource and preparation tool.
