I can count 5 guys on our roster right now that can cover elite wings. Paul, Ray, Kevin, TA and Scal.
Paul will be in the game when it matters most, and I think the other 4 can give someone like Lebron a different look for 6-8 mpg and be mildly effective. It's really more the job of our team defense than any one guy individually that will contain the likes of Lebron and Kobe.
Now consider that we really only have Perk and KG that can legitamatly match up against the likes of Big Z, D.Howard, Yao, and Duncan over a 7 game series. Considering our roster will likely only allow for one pickup, I think the obvious area of need is a 6'10"+ backup center.
I am still holding out hope for PJ, we do still owe him a ring ceremony... What a way to kick off his second comeback, eh?
