Can I use deck pier blocks instead of footings?

Why deck posts should not be set in concrete?

A deck post should always be placed on top of footing, not inside concrete because it can break. Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will result in the wood breaking the concrete.
