Keeper Watch (Intro and Miles Plumlee)
Pick and Roll Coverage and Help Defense
As far as his actual defensive movement, it's usually pretty go0d. He can struggle at times versus teams which run some misdirection into the PnR such as Portland (or San Antonio, even though he recovers to block Duncan on that play):
In help defense and rotation situations Plumlee is generally well-schooled as one would expect from a former Duke player and graduate of Pacers Academy. He is occasionally prone to ball-watching as in the Portland example above. That said, he is extremely active and hard-working. Plumlee leads the league in opponent's shots he contests at the rim, averaging 10.8 per game, while being the only player averaging 10 or more contests to play fewer than 30MPG. Of the shots he does contest, he is slightly above average, ranking 20th (out of 54 big men) in terms of opponents FG% on those shots, and is tied for 9th in the league in BPG, and does it all without fouling very much (98th in the league in fouls per game). Unsurprisingly, given these attributes and the general struggles of the rest of Phoenix's bigs, he leads the team in individual D rating (not my favorite stat across teams, but possibly instructive within a team), scoring several points/100 higher than any other Suns regular.
