He definitely needs to play more minutes and close regularly. He's the closest thing this team has to a second option, plus he's highly motivated and still has enough physical ability for that to matter.
you could argue it's semantics... and I will just leave it at that... he has been a big this season for the Spurs which matters when one talks about his minutes vs other people etc. Just hasn't been a wing this year... but don't even want to argue about something that is evident.
The thing is, in many instances there is no such thing as two big positions anymore. This team is a perfect example of that. Other than when Aldridge and Gasol play together (which is the first 6 minutes of the 1st/3rd quarters and occasionally clutch time), they just play with one traditional big.
