Starting Gay in place of Cunningham and letting Bertans play the backup 4 and Dante play behind DeRozen seems like the obvious move.
Cunningham gets in the way in the starting lineup; DeRozen and Aldridge aren't threats outside of 18 feet and teams playing off of him don't help things
White-Forbes-DDR, Gay, LMA
Mills, Beli, Cunningham, Bertans, Gasol
Beli definitely looks more trigger happy now than his first stint with the Spurs, it's looked ugly in large part because he's hitting only 32% on 3's and has even been missing open 3's in addition to taking a bunch of sketchy shots.
