As far back as last year, when Rajon Rondo was named to the NBA’s all-defensive second team for the second time — he was a first-teamer in 2010 and ’11 — the Celtics point guard wasn’t even considered the best defensive guard on his own team.

That informal honor belonged to Avery Bradley, who was in the process of showing the league why that was the case when he went down for good with a separated shoulder during the Eastern Conference semifinals against the Philadelphia 76ers. The C’s took Miami to seven games in the conference finals, and many wondered what the result would have been if Bradley had been available to guard the Heat’s Dwyane Wade.

Well, in what has become a right of passage for the Celtics’ best young guards, Bradley finally cracked the list yesterday when he was named to the league’s all-defensive second team. In addition to receiving 10 first-team votes, Bradley was the leading vote-getter on the second team.

The Memphis Grizzlies’ Tony Allen, who started his climb to defensive excellence with the Celts, was the leading vote-getter on the first team with 53 points, one ahead of Miami’s LeBron James, the NBA MVP. Allen, who along with James garnered 25 first-place votes, is generally considered the best perimeter defender in the NBA, though teammate Marc Gasol was named defensive player of the year by NBA writers due to some impressive big man stats. Gasol was not held in as high regard by the league coaches, who voted for the all-defensive teams and relegated the Grizzlies center to the second team.
