Spurs need a big man more than another guard.
When matched up a healthy Laker team, the Laker big who isnt being guarded by Duncan should dominate.
Gasol against Thomas? Ownage
Bynum versus Thomas? Ownage
Plus Bynum is longer and bigger than Chandler who gave Duncan alot of trouble with his length.
In terms of a match up against the Lakers, I dont see this supposed signing as a big deal.
