The value for McGee hinges on how badly the team needs immediate help IMO. I can see McGee being the best guy on the wire by a bunch, but the wait could be too much for a middle of the road team. He's not exciting though, you're right, and wasn't playing well before he went down either, so there's that. For roto league or a good mid-size std league I might give McGee a look. Maybe.
I don't play in any leagues where Gasol is on the wire, so I wouldn't know what that's like.
