Douglas Jones-US PRESSWIRE
What makes Howard such a terrifying defensive presence is not only his rebounding ability, but his propensity to reject shot attempts from all challengers.
Howard led the league in blocks in back-to-back seasons (2008-09 and 2009-10), finishing with nearly three blocks per game in each of those seasons. He's never finished a season with fewer than 115 blocks, as his footwork allows him to rotate around the rim to challenge defenders at all angles.
Statistically speaking, Bynum doesn't have anything close to Howard's shot-blocking resume. He's only averaged above two blocks per game twice in his career, while Howard has done it each of the past five seasons.
Keep in mind, though, many of Bynum's early years were marred by injury. Per 36 minutes, Bynum's block averages actually dwarf Howard's in four of the past seven seasons, while Howard holds the advantage in two. Each player finished with exactly 116 blocks last season, although Bynum appeared in six more games than Howard.
Bynum is a force to be reckoned with around the rim, but he lacks Howard's quickness and footwork. The Philadelphia 76ers lack any other legitimate shot-blockers, unless you count Kwame Brown (and you shouldn't), so Bynum will have plenty of opportunities this season to prove that he can be as dominant of a shot-blocker as Howard.
For now, though, Howard gets the gold star here.
