Rebounding is 80% effort. One of the years on my high school team we had a shorter team, and rebounding was an issue. I was a 6'2" PG/Combo guard but I ended up playing 4 positions, and I was one of the better rebounders on the team (average just under 7 rpg). Our coach preached this, that effort and technique can overcome pure physical size and he was right. We consistent out-rebounded bigger teams because we drilled it and it was part of our identity. Our biggest player was 6'5" and he was one of the best rebounders in the state that year, consistently over anyone at 6'8" and bigger. Our coach taught us that, that rebounding is 80% effort and technique. And he was right. Frankly at the NBA level it's about making it a priority for each player. That's what the clippers did and it worked. We only have about 2 or 3 people really concerned with it at all, but everyone needs to buy in. And yes, we need much more length on the wings.
