He ended up on Mudiay for a while and, while Mudiay wasn't all that effective on his own, Ben did seem to pressure him well.
More importantly, there still were some switches on defense, and in one particular instance down the stretch I remember Ben was switched on to Gallinari and held his own.
What really hurts, in my mind, is when Cousins draws the swarm down low, actually succesfully passes out of it, and the Kings swing the ball around to the open shooter and the shooter misses. Ben may have done this, but I distinctly remember Collison missing a couple of these from the corner (Collison otherwise had a great game, though).
