I would play motion and 2-3 but seriously you need to get a big guy with at least an 8k salary. (It only costs about 40k max on the TL for a 25-28 year old big guy with around a 10k salary). I promise you your team will be much much better if you get a couple big guys on the TL because then you can play strict M2M for defense and usually do better in the defensive and rebounding ratings.
