Yeah, don't limit yourself to baseline spin cheese with Griffin though, I found that treating him like a perimeter player and isolating opposing 4s on the perimeter worked wonders. Taking advantage of his elite ball-control (for a big) and overall athleticism, I used a combination of spins, crossovers and behind the back moves and had a ton of success against every 4 in the challenge. Also, using face-ups in the post worked pretty well for me too. The quickness advantage proved to be too much, even against Malone and KG (where a strength advantage probably factored in as well).
